Docket Cache is not a magic pill
We wish it were, because that would make it easy to sell. But the truth is, many things affect how fast a WordPress site loads, and caching is only one of them. Installing Docket Cache on its own won't give you an A+ score on a page speed test.
Used the right way, though, Docket Cache can make your pages load faster and take work off your server. It is a useful tool for making WordPress run better.
How does it work?
There are many ways to cache a website, such as page caching, CDNs and object caching. Docket Cache is an object cache plugin. It also comes with extra options to speed up your site. Because it handles object caching itself, you can't use it together with another object cache plugin.
Docket Cache saves WordPress data as ready-to-use PHP files. WordPress can load this data straight away, without converting it first. OPcache then keeps these files in memory, so reading the cache is almost as fast as a memory-based cache like Redis.
Works where your site runs
Docket Cache works on most hosting, whether it is a standard WordPress install, a multisite network, or a custom setup like Bedrock. This is one of the reasons we chose to cache to files.
Because it uses files, you don't need extra services like Redis or Memcached. If your site runs on a VPS, you can put the cache on a RAM disk to make it even faster. And thanks to OPcache, Docket Cache reads and writes files only when it has to.
