Caching is a great start, but there is more to maximize your site speed. Find out how much your cache speeds up your site and make it blazing fast with Jetpack Boost, the easiest WordPress speed optimization plugin developed by WP Super Cache engineers.

The following recommended settings will be enabled:

  1. Caching disabled for logged in visitors.
  2. Simple caching.
  3. Cache Rebuild.
  4. Interval garbage collection every 10 minutes with a cache lifetime of 30 minutes (if not configured already).

These settings can be modified on the Advanced Settings page.

Cache Tester

Test your cached website by clicking the test button below.

Note: if you use Cloudflare or other transparent front-end proxy service this test may fail.

  1. If you have Cloudflare minification enabled this plugin may detect differences in the pages and report an error.
  2. Try using the development mode of Cloudflare to perform the test. You can disable development mode afterwards if the test succeeds.
