The Blitz plugin provides intelligent static file caching for creating lightning-fast sites with Craft CMS.

It can highly improve a site's performance by reducing the time to first byte (TTFB). This reduces the load time of the site as well as the load on the server. Google recommends a server response time of 200ms or less.

Although the performance gains depend on the individual site and server setup, the following results are not uncommon (on a 5 Mbps cable connection with 28ms of latency):

  • 650ms (without caching enabled)
  • 400ms (with caching enabled, without server rewrite)
  • 120ms (with caching enabled and server rewrite)
