Need for Speed?
This plugin handles the wordpress/php side of a statically cached nginx-fronted wordpress (or wordpress mu) site. It makes WordPress emit an “X-Accel-Expires: 0” header when a user is logged in or has taken actions that should cause them to get a customized page on your frontend. This – along with the nginx configuration below – will ensure logged-in users aren’t impacted by your static nginx cache.
Why would you want to statically cache wordpress with <a href="http://www.nginx.org" rel="nofollow ugc">nginx?</a>
<ul>
<li>INSANE performance. Hardware that could generate 6 pages / second can now generate many thousands.</li>
<li>Low resource usage. Even on very busy servers, nginx uses only a handful of RAM.</li>
<li>Unobtrusiveness. You plop nginx in front of wordpress and that’s pretty much it. This plugin (and nginx) is all you need to make your site digg- and slashdot- proof.</li>
<li>Stability. Nginx is rock solid.</li>
<li>Faster is better. All the web gurus agree – visitors like faster sites, even when the differences are slight.</li>
<li>Do more with less. Using a frontend proxy lets you keep your heavy wordpress apaches lightly loaded, letting you handle more concurrent connections and use less RAM.</li>
</ul>
We’ve been using a caching nginx proxy at the fairly busy <a href="http://blogs.law.harvard.edu" rel="nofollow ugc">blogs.law.harvard.edu</a> since September, 2009. The results have been dramatic: we’ve halved the amount of RAM we need, doubled our outgoing network throughput (nginx is fast!) and have had essentially no significant load spikes.
Drawbacks
There are a few.
<ul>
<li>Plugins that rely on php code running on each page view won’t work properly. This is similar to wp-supercache or any of the other static caching plugins. Stats, image rotation, etc. You should implement these features via javascript or third-party services, depending. </li>
<li>You need to install and configure an nginx frontend proxy – but see the “installation” tab. It’s really not that hard.</li>
</ul>
Notes
<ul>
<li>It is completely harmless to install and activate this plugin before you’ve got the nginx side set up.</li>
<li>YOU MUST keep this plugin activated as long as you’ve got an nginx frontend proxy active – otherwise, you’ll end up caching too much of your site, and authenticated users won’t see customized pages.</li>
<li>This plugin helps speed up access for authenticated users mainly because it makes all other traffic a negligible resource drain. I suggest installing <a href="http://php.net/manual/en/book.apc.php" rel="nofollow ugc">apc</a> (or another opcode cache) and – alternatively – a wordpress object cache. Definitely install an opcode cache – leave the object cache for later. You may find you don’t need it!</li>
</ul>
<h3>The Future</h3>
This plugin could be set up to allow you to manage caching policies entirely from a wordpress control panel. We’d do this by manipulating the timeout in the “X-Accel-Expires” header based on the type of resource that’s been requested.
It’d be nice to de-cache when pages change via some call from the backend to the nginx frontend.
