WordPress Caching: What’s the best Caching Plugin?

Your WordPress blog getting sluggish? Caching is a great technique for speeding up your blog and the WordPress community has a lot of caching plugins to choose from. Lets review each one and find out which caching solution will work best for your WordPress blog.

Newer versions of these plugins may be available

These benchmarks may not accurately reflect the current version of any of the plugins listed below. From this post, you should take away some important abilities of these plugins, but attempt to do some testing of your own.

For those who ask, Tutorial9 uses W3TC. We have not done extensive testing, but it works incredibly well for us.

What Is Caching?

Each time you visit your blog, WordPress will go through a sometimes lengthy process to build everything you see. First it will process the PHP code which will make numerous calls to your database and finally output HTML for your web browser to display. On some blogs this could happen between 20 to 200 times per page! WordPress has often been criticized as slow but we can change that by enabling caching.

If you enable caching only the first visitor will go through this entire process. The caching mechanism will save the data and then serve every subsequent visitor the final result. Thus speeding up WordPress by a huge factor. Trust me, you want it and your visitors will thank you for using it.

Benchmarking

I will be using Apache Benchmark to grade the effectiveness of each caching solution. Apache Benchmark works by producing a large amount of requests to your website and then reporting back the average requests it was able to make per second, the average time it took per request and the transfer rate of data (among a lot of other data).

I will be running 1,000 requests at 10 concurrent or the number of parallel requests then taking the average of 3 tests ran at various times of the day. I will be using WordPress 2.9.1 with a few popular plugins activated: Akismet, All in One SEO Pack, and Google XML Sitemaps. My test blog is running on a shared server with a low amount of normal traffic so the benchmarks don’t get too disrupted. I’ve loaded my test blog with an average amount of content, images, stylesheets and javascript files.

Starting Statistics

I’m not going to test on a fresh install of WordPress because I want to simulate a real world every day blog rather than an unrealistic empty blog. This is the same reason I decided to host the test blog on a shared server. My goal is the average and most of us probably have our blogs hosted on a shared server with minimal optimizations specifically geared towards WordPress.

No Cache

First we are going to run a benchmark with caching completely disabled. This will give us a control test to compare the performance of each plugin.

Data - No Cache

Yikes, 13.96 requests per second is pretty bad but I can’t complain. WordPress is really slow without any performance tuning and my test blog is running on a $10/mo shared server account. Sometimes you really do get what you pay for. Lets see if we can get more out of this not so ideal predicament.

WP-Cache

http://wordpress.org/extend/plugins/wp-cache/

WP-Cache is a simple and aged cache plugin. Although it has been around for a long time it also hasn’t been updated in a long time.

WP-Cache was an easy plugin to install but it does create a few files outside of the plugin directory and doesn’t clean up the mess when you uninstall. Some users may get the error message “sem_get” on the top of every page of their blog. Just edit the file wp-content/wp-cache-config.php and uncomment the $use_flock line. That will fix the error message if your server doesn’t support the sem_get file locking command.

Data - WP-Cache

WP-Cache is tried and true. Even for its age and lack of updates, WP-Cache is still a contender and a very light weight one at that. Overall performance and installation could definitely be better though.

WP Super Cache

http://wordpress.org/extend/plugins/wp-super-cache/

WP Super Cache is a very popular plugin once based on the previous WP-Cache plugin and it is routinely praised among many WordPress communities.

Overall it was somewhat easy to install and uninstall. Cleans up its own mess when deactivating which is always nice. I got a “gzuncompress” error message only once after activating but it didn’t appear to affect operation of the plugin. You have to manually create an .htaccess file but at least it gives you some code to copy and paste.

This plugin has a long page of endless options and the user interface could certainly use some cleaning up. Be sure to follow the directions carefully after activating. Especially pay attention to the directions on creating a proper .htaccess file.

Data - WP Super Cache

With Compression Turned On:

Data - WP Super Cache w/ Compression

Be Careful Enabling Compression

If you enable WP Super Cache Compression and your server already has compression enabled or doesn’t support it then you will get a lovely blank page of death or just a lot of garbage printed on the screen. Use with caution.

Something seriously wrong is obviously happening when compression is enabled. Despite what the people say, WP Super Cache isn’t very super. In my opinion it is a complicated version of WP-Cache with only slightly better performance. With numerous reports of blank pages of death, I am hesitant to install this plugin on an actual blog. On top of it all this plugin doesn’t seem to play nice with others. Improper configuration and/or a bad plugin combination can lead to a drastic decrease your performance. It is sad but true.

WP Widget Cache

http://wordpress.org/extend/plugins/wp-widget-cache/

WP Widget Cache is a plugin geared toward those with heavier widget use. My test blog, only using the default widgets, may not have completely benefited from this plugin. The author recommends running this plugin along with either WP-Cache or Super Cache so I will run 3 tests: Standalone, with WP-Cache and with WP Super Cache.

WP Widget Cache was very easy to install and uninstall. Just clicked activate and since my wp-content folder was writable everything installed automatically. In order for this plugin to work you must goto your Widget settings and set the expire amount field on each widget.

Standalone:

Data - WP Widget Cache - Standalone

With WP-Cache:

Data - WP Widget Cache - WP-Cache

With WP Super Cache:

Data - WP Widget Cache - WP Super Cache

This plugin would be useful to those who use database intensive widgets on every page. Other cache plugins will process then cache your widgets for every page. This plugin will cache your widgets and serve your other cache plugins a copy as they save each page.

Some Widgets Should Not Be Cached

If your widgets are dynamic or change on every page then of course this plugin will be of little use to those widgets. Make sure you set the expiration to empty or 0 seconds on your dynamic widgets to prevent caching.

DB Cache

http://wordpress.org/extend/plugins/db-cache/

The DB Cache plugin works very different than the others. Instead of building and saving your pages it saves the database queries instead. This plugin is available in many different languages.

Installation was very easy and the user interface is simple and clear. Cleans up great upon deactivating.

Data - DB Cache

DB Cache is more for the server administrator. Caching pages, especially if you have a lot of pages on your site, can be very CPU intensive and they take up a lot of disk space. If you run and optimize your own web server then this plugin will be good to you. Although if your blog is on a shared server or has fewer than 500 pages then this plugin may not be as beneficial to you.

DB Cache Reloaded

http://wordpress.org/extend/plugins/db-cache-reloaded/

DB Cache Reloaded is similar to DB Cache. In fact it is a fork of DB Cache because the author didn’t think DB Cache was updated quick enough. This plugin is also available in many different languages.

Installation was very easy and the user interface is simple and clear. Cleans up great upon… ok, ok it is really similar to DB Cache. Lets just call it DB Cache Reloaded… oh wait, it already is.

Data - DB Cache Reloaded

Just think of it as the same as DB Cache but better.

1 Blog Cacher

http://wordpress.org/extend/plugins/1-blog-cacher/

1 Blog Cacher is a lightweight and simple caching plugin. Not very popular but I’ve seen it recommended on more than one occasion.

Installing this plugin was annoying. I had to manually create the folder wp-cache, move the file 1blogcacher2.0.php to the wp-content/plugins folder and move advanced-cache.php to the wp-content folder. The user interface is terrible and the options are not editable through the admin settings. Everything must be configured directly in the advanced-cache.php file. Terrible for a multi-user setup or those who don’t want to FTP into their account every time they wish to make a configuration.

Data - 1 Blog Cacher

I don’t think this plugin even works despite appearing to have done something by adding a message in my source. The author says its version 2.0.2 but it almost seems like a plugin that is still in beta. Easily the worst caching plugin I’ve encountered.

Hyper Cache

http://wordpress.org/extend/plugins/hyper-cache/

Hyper Cache is a new caching plugin out in the community. It is geared towards the everyday blog or those hosted on low cost shared servers. Also available in many different languages.

Installing was a simple upload and activation. This plugin has a lot of great configurations and organized appropriately in a clean user interface.

Data - Hyper Cache

Hands down the fastest caching plugin I’ve reviewed and surprising for how light weight it is. It may just be me but my blog just seemed to click on rather then load with this plugin enabled. Definitely for those hosted on a shared server or who are looking for as much caching performance from a plugin as possible. The development around this plugin looks very active too. A definite must have plugin especially if you plan on configuring your own additional performance tweaks such as minifying, db caching or compression.

W3 Total Cache

http://wordpress.org/extend/plugins/w3-total-cache/

W3 Total Cache is the mother of all caching plugins. It is huge, well documented and packs in an impressive amount of performance configurations all into one plugin.

Installation was surprisingly easy. With all the options available I thought I was going to be here all day configuring this beast. After activating it automatically best guessed an optimal configuration. Great for those who just want to install and go.

Data - W3 Total Cache

If you’re looking for a plugin that does everything then this plugin is your golden ticket. From multiple methods of page caching, minifying, database caching, content delivery networks… this plugin does it all. They even have support request available and built right into the plugin.

Now to avoid sounding too much like a car salesman lets review the cons. First, it is huge. Even though disk space is becoming less and less of an issue there are some blog admins out there that either don’t have or want to spare the space. Second, it is fast but not the fastest caching plugin out there. Especially if you disable the minifying and compression built into the plugin. Then it runs on a more equal footing with the other plugins reviewed here.

Do It Yourself Caching

Who said you have to use a plugin to cache your blog? Caching pages yourself can sometimes be the best solution, especially for those high traffic and rarely changing pages in your blog. It does take a bit of manual labor though.

First create a folder called cache in your wp-content folder. Visit the page on your blog that you would like to cache then view the source. Copy the entire source into a file named relevant to the page you are caching. For example if I want to cache my about page I would name the file about.html and put it in my wp-content/cache folder.

From here we need to create a .htaccess file in your root WordPress folder. Copy the following code into your .htaccess file.

<IfModule mod_rewrite.c>
RewriteEngine On
RewriteRule ^about$ wp-content/cache/about.html
</IfModule>

Using mod_rewrite we are telling the server to deliver the contents of the wp-content/cache/about.html file when someone goes to http://yourblogurl.com/about. I suggest learning more about mod_rewrite before manually caching a bunch of your pages. A handy solution though because from here you can perform other tweaks directly to the file such as minifying. Manually creating the files will also save a great amount of CPU load, which is critical for high traffic servers.

Data - Do It Yourself

Although it is a lot more work then using a caching plugin; caching pages yourself does deliver high performance. Just remember your manually cached pages will not and can not be updated through WordPress and you must continuely update your cached pages by hand. This is a viable solution for those static high traffic pages but not an ideal solution for most bloggers.

Combining Plugins

Combining some of the plugins can lead to an increase in performance such as Hyper Cache + DB Cache Reloaded. Although some combinations will greatly decrease performance such as WP Super Cache + Anything. Try combining and see what works for you.

What Not To Cache

There are a few elements to a blog that you should avoid caching. Such as ads, feeds or any dynamic content obtained using php or a server side system. The whole point of caching is to save time by avoiding server side processes. If you have any content that needs to change for each visitor then you should avoid caching that page or content.

Don’t worry about your Google Ads or BuySellAds. Those ads are delivered using javascript and caching won’t affect the delivery of those ads. Most javascript based systems will not be affected by caching since they are client side scripts; not server side scripts. Although it is always good practice to double check to ensure your dynamic content is not being cached.

Final Results

Data - Results

Overall the best out of the box cache plugin configuration in my opinion is: Hyper Cache + DB Cache Reloaded. Despite the allure of W3 Total Cache’s professionalism and only slightly less admired performance, I prefer to retain some manual control over my blog. For those on a medium priced shared server or if you like the idea of installing and forgetting, the W3 Total Cache plugin will be your ideal choice.

A lot of people still use WP-Cache and WP Super Cache. They are still respectable WordPress caching plugins but consider trading up for Hyper Cache or W3 Total Cache. These newer caching plugins prove better performance and install/config much easier and cleaner. Also the development communities around these newer plugins are much more active and attentive to their users.

I hope I’ve helped you in choosing the best caching solution for your WordPress blog but this is only the beginning. There are so many more techniques to improve the performance of your blog. Caching is a great first step in preventing your blog from crashing during a flood of traffic.

    Have a question… I’ve used both w3 and wp super cache.

    If I have a low server load on my shared server running wordpress with traffic under 10,000 page loads a day; w3 blows supercache out of the water

    Once I start getting to around 150K pageloads a day running w3 my server is basically nonfunctional. With wp supercache it’s still not even sweating…

    I’ve tried both disk and memory based caching in w3 and database caching on and off; makes no difference when exp high traffic.

    Any ideas?

    Quick Cache is another cache plugin you might want to test. I find this plugin easy to use and doesn’t give ‘headache” like your website

    For all the cache plugin, setting browser cache setting to on make a lot of difference on the speed.

    Thanks for the article. I’ve only ever used W3 Total Cache so I can’t comment on others, but it seems as though you left out some important information. Was all caching enabled (Page/Database/Object/Minify) and which method was used (Disk (Basic/Enhanced)/Memcache/etc).

    I personally use W3TotalCache with Memcache and it seems to be faster than Disk cache, although I never actually did benchmarks on the two.

    How would caching plug-ins compare to CDNs like Amazon cloudfront or something like Cloudflare? Cloudflare is pretty easy and free, I notice response times from my websites speed up at least 150% but I didn’t do a comprehensive test.

    Any views on how something like that would compare to a caching plug-in? Would it make sense to combine such a service or would it just mess up things?

    Thanks for doing the tests and sharing, really very interesting stuff!

    Kyle: Thank you, for this SUPER comparison of WordPress Caching PlugIns! Just what the doctor ordered for me! Today, for the first time, I installed WordPress. From your clear reviews and suggestions, I chose Hyper Cache. My only surprise was that I needed to add a line to the wp-config.php file, to enable the WordPress Cache system, which took me a few minutes to figure out how to do. Kudos to you and keep up the great work! Your tutorial is greatly appreciated!

    Wow what a great primer. I have almost no experience with caching (and very little understanding of how it works), so this was a really helpful overview. My site has become exceedingly slow, so I decided to try W3 Total Cache based on its popularity. While obviously very comprehensive, it was also a little frightening. ;)

    After reading this I’m giving Hyper Cache a shot instead. Maybe later when I have time to read through some of the documentation for W3 Total Cache I’ll try again. Anyway – many thanks for a very useful article!

    Nice compilation! I’ve used W3 Cache, had some problems, then uninstalled only to have it take the site down entirely.

    A nice alternative is Really Static, which generates static pages on your WordPress site kind of like Movable Type does out of the box. Combined with other optimization, it has most of my page loads under five seconds. No complaints so far.

    I help run a couple of high-load wordpress sites. Interesting review. I’d agree with the above commenter, you shouldn’t have had that bad a performance with supercache and compression, it only affects anything on cache-page generation. After gen, it should be lightning fast.

    Also, I know the supercache dev is active, and is a nice guy. Certainly, he’s helped us with stuff on one of the sites.

    i run a fairly busy american idol blog and have been running caching for quite sometime. i am on a quad core dedicated with 6GB RAM. I have a local memcache server, an external memcache server and Xcache installed.

    I have tested every single caching plugin i can find for wordpress with the above setup and wp-supercache still performs the best. i have page load times less than .900 all the time and i am running 47 plugins.

    right now i am testing DB-cache reloaded combined with hyper cache and i am seeing nothing better.

    did try the new quick cache last night. worked great except it wasn’t what i was looking for. there was in issue with a plugin i run. won’t go into that but everyone should give it a look and try it out

    I’m honestly surprised WP Super Cache did so badly. If configured correctly it should be just as fast with compression on or off. Cached files are stored compressed so once cached they’re served like any other files.

    If you didn’t configure it correctly you might have been serving the cache files using PHP rather the mod_rewrite .htaccess rules. Those should be blazingly fast.

    Hi,

    I’m in the process of setting up a blog, and already tried the Super & Total plug-ins. And I was disappointed about the gain in speed.
    Thanks to this article I discovered the Hyper plug-in. It made my site 2x as fast as the Super & Total solution !

    Do you know if the cache plug-in selection depends on your hosting company, and its default server settings? That could explain why for some the other plug-ins are the way to go.

    Thanks !

    The ’1 blog cacher’ is definitely one to avoid as I found out. It doesn’t separate mobile users, it just shows the cache to them even if you have a mobile version of your site. And if a visitor lands on a page via a cellphone first it caches that and shows it on your normal site, as it did with my homepage once! Couldn’t believe it! And it also breaks the ‘post preview’ function so you can’t preview posts before publishing. For these 2 reasons alone the plugin is badly flawed and should be avoided.

      Some of the caching plugins listed above also have gzip capabilities. It can cause problems if a plugin gzips content that has already been gziped. You’ll notice quickly though when your pages show up as random lines of characters. I would either disable gzip in the plugin you choose or remove your previously setup gzip solution.

      As for WEBO Site SpeedUp… I try to avoid solutions that are not free and open source. Not just because I’m cheap but because I believe code that is freely open for critique and modification will always be better. Plus it just seems wrong to pay for a caching plugin that runs on WordPress, running on PHP, running on Apache, running on *nix …all of which are free and open source.

    I tried to get Hyper Cache running for a client (dredgingtoday.com), but I had some trouble with the plugin not being able to write the cache files. The plugin had no problems on my development server, but the production server has some weird configuration which the plugin apparently didn’t like.

    I decided to use Quick Cache for this site, which looks pretty solid and had no problem with the weird configuration of the server. But haven’t done any real benchmarking with it at this moment.

      My guess would be your plugins/hyper-cache/cache folder on the production server doesn’t have write permissions to create or write to the cache folder. You could manually create the folder and chmod it to 777. A better option would be to have the server configured to run php as a user to avoid world-writable files. suphp is a great solution for doing this.

      Let me know how it goes with Quick Cache. It looks like an great overdue upgrade that WP Super Cache has been needing.

      Hi Pontus,

      I’d say WordPress is really useful because it allows for a wide variety of content management.

      You can easily edit your site’s content in the backend, WordPress is a powerful framework and it’s easily configurable.

      You need to have a basic understanding of HTML and PHP to create your own template, but there are many, many tutorials that will help you out.

      Chris Coyier over at CSS-Tricks.com has done many articles and screencasts on this subject, so it might be worth checking that out.

    The other thing that comes to mind (and I believe the w3edge guys emailed you privately about) is the lack of information on how the tests were performed, how we can repeat them against our own blogs, and like Sean said above, the specs of the machine the site is hosted on.

    I’ll also +1 Sean’s recommendation of utilizing a reverse proxy cache. If you have the ability (i.e. skills to implement, and a VPS or Dedicated machine you can install software on) you can add to the caching awesomeness provided by these plugins by having a reverse proxy at the edge. Nginx, Squid, and Varnish are all great choices here, aren’t too terribly difficult to implement and store the results of your pages in MEMORY. If you can hand a “pre-cached” version of your page off to a reverse proxy cache, you can almost double your throughput in most cases.

    Definitely with Eric Marden on using (or using in addition to) siege. It’s pretty powerful, and from what I understand, a little more accurate than ab.

    I love that you ran the tests against a server that more imitates an actual application – instead of just a base WordPress install with the Kubrick theme and no plugins.

    It’d be great if you could share the physical specs of the machine you were benchmarking against, as well as relevant configurations (relevant lines from Apache confs like modules used, VirtualHost settings, etc.).

    I know some of the comments have pointed out benchmarking against cache engines that use memcache as well (like Batcache: http://wordpress.org/extend/plugins/batcache/).

    While I realize the goal here is to just benchmark against plugins, other users may be interested in using something like Varnish (although it requires some *nix knowledge as well as an environment that would allow you to set it up).

    All in all – great post. Thanks for sharing.

      Thanks for the feedback Sean. There is a lot more technical developers here on tutorial9 than I anticipated. I’ll definitely have to widen my benchmarking methods and discuss more details in my upcoming posts.

      The blog was hosted on a shared server farm in Fremont, CA. The server has an Intel Xeon X3360 (Quad Core 2.83Ghz) with 8GB of RAM and connecting through multiple full gigabit ethernet. Running Ubuntu, Apache2, PHP5.2.4 with the following modules loaded: core mod_log_config mod_logio itk http_core mod_so mod_alias mod_auth_basic mod_auth_digest mod_authn_file mod_authz_default mod_authz_groupfile mod_authz_host mod_authz_user mod_autoindex mod_cgi mod_dav mod_dav_fs mod_dav_svn mod_authz_svn mod_deflate mod_dir mod_env mod_expires mod_headers mod_include mod_mime mod_negotiation mod_perl mod_php5 mod_rewrite mod_setenvif mod_ssl mod_status mod_userdir

    Excellent post Kyle. I use WP-super cache and WP-minify which is also a performance booster. I haven’t noticed any collision between these plugins (you said super cache shouldn’t be combined with other plugins).

    I’m curious, which caching backend did you enable for W3 Total Cache? If you are caching to the file system, then it will probably be slower, but if you enable caching to APC and/or Memcached, you should be able to squeeze out a lot more performance out of this plugin. Add in the fact that you can enable CDN support for static files, and your requests per second should shoot WAY up.

    Did you using W3 Total Cache in the ‘disk enhanced mode’ or the default?

    Did you copy code from the .htaccess file in /w3-total-cache/ini into your root .htaccess file? This enables http
    compression and client-side (browser) caching of files that W3 Total Cache does not handle.

    How about some memcached-based caching systems? I’ve got WordPress set up on two servers behind a load balancer, and the caching sysems based on saving a static file don’t work for my setup.

    I use W3 total cache and love it. One nice feature is that if you do move to a VPS or dedicated server you can install APC, etc and set W3TC to use memory to cache things vs disk. ON shared hosting? You can just use disk since you usually can’t use APC there. That flexibility is very nice since it lets me use one plugin and tailor it to the client’s environment.

    Hi you say “Combining some of the plugins can lead to an increase in performance such as Hyper Cache + DB Cache Reloaded”
    I thought that Hyper Cache creates a static page and shows that to the user. So Im not sure why or how DB Cache Reloaded would make it even faster.
    I must be missing something?
    What does DB Cache Reloaded do that Hyper Cache does not do?

    Also I had to disable the “bad behavior” plugin as it conflicted with Hyper Cache.

    Thank you for your help, great post.

      DB Cache Reloaded only caches database queries. When running in tandem, DB Cache Reloaded will make Hyper Cache cache your pages more efficiently. It will reduce the load on the server and speed up the caching process by reducing the amount of database queries.

      If your blog has a lot of pages, uses a lot of plugins and/or widgets then running DB Cache Reloaded along with Hyper Cache will be more beneficial to you. Otherwise if you don’t then running DB Cache Reloaded won’t hurt performance, so I recommend the two.

    I use Super Cache because I’m on shared hosting, and the overhead for W3 Total makes less sense as the extra features are unusable or frowned on (compression uses processor) by the provider.

    That is seriously some in depth comparison done by you, Kyle. From the comparison we discovered that Hyper Cache speed the blog the best but still I will stick with my current plugin – W3 Total Cache..I dumped WP Super Cache as it was having very less features..

    Also, as I am also using CDN and hence I found W3 Total Cache the best & easy plugin to integrate CDN settings in my blog.

    Interestingly, I also wrote an article yesterday to speed up wordpress blog – http://www.smartbloggerz.com/2010/04/how-to-speed-up-wordpress-blog-in-3-simple-steps/

    It revolved around W3 Total Cache and use of CDN with it.

    You should also point out that you are testing only the caching features. Some plugins, like W3 Total cache, also offer css and js minification and also compress those files into two files, so there will be more speed gain by having fewer files/requests to deal with.

    I don’t think this post is actually helpful. You don’t even discuss the CDN functionality of W3 Total Cache, nor really explain why the plugins are different. If you want to do a comparison you should have actually done a 1 to 1 comparison of features so readers would actually know how to make a decision.

      First off it doesn’t matter how old the plugin is, if it’s still the better product.

      Also I would like to say I’ve used w3 with “enhanced disk” for over a year and had some improvement. It definitely was way better than Supper Cache (for many reasons), but HyperCache has cut my load time in half. I believe these stats to be very accurate, especially since my own load times improved by similar amounts.

      The difference was insignificant between Hyper Cache alone and Hyper Cache + DB Cache Reloaded. If my test blog hit the database more frequently then difference would probably show more. Adding DB Cache Reloaded won’t hurt your performance if your blog isn’t database intensive but will increase performance if your blog is hitting the database frequently.
