Fast and easy

This plugin speeds up your site considerably without the hassle of installing Redis or Memcached. In fact, I think this should be part of WordPress core! ??

I’ve been testing this on a busy site (3000-5000 visitors/day with many logged-in users), and it’s doing fine.

I used the Redis Object Cache plugin before this one, but I find this one is easier to manage (no Redis installation required) and contain (the cache files are hidden files within your wp-content dir). Thanks to the cache files inside your site’s dir, installing this one on all your sites is more manageable. To illustrate: when you have multiple sites, you must manually administer and change the database number with the Redis Object Cache plugin, and it’s not a setting in the UI but a config file change. (And: Redis is limited to 16 databases).

I don’t have hard stats, but the site doesn’t feel slower or faster than using Redis for caching. I do think it helps a lot when your server has plenty of spare memory, so Linux’s file caching system can cache the SQLite db.

I glanced over the code (I’m an experienced software engineer), and the plugin seems well-written.

If you’re looking for a quick and easy way to speed up your entire site, including the admin area), this is a no-brainer.
