WordPress Core Contributor Konstantin Kovshenin has released a new page caching plugin called Surge. Searching the WordPress plugin directory, you will find hundreds of caching and cache purging plugins, but this one stands out from competitors in that it requires no configuration. The plugin starts working as soon as it’s activated, and there are no options.
What kind of performance improvements can you expect with Surge activated? Kovshenin’s tests indicate that WordPress site performance on cheap hosting can be significantly improved with the plugin:
Surge stores cache files on the filesystem, leveraging the Linux kernel page cache for efficient in-memory caching and invalidation. In various load tests, Surge has shown to easily handle 1000-2500 requests per second at 100 concurrent, on a cheap single-core virtual server with only 1 GB of memory. That’s over 70x faster than a stock WordPress install with a default theme and no plugins.
