"All I can say to conclude is that this is worth playing with, and that Symfony2 really doesn't disappoint with regard to speed."

A Symfony plugin for using Redis as a cache backend.

The very point of caching is that it's faster and less resource intensive to deliver cached data than creating it on the fly. With existing cache solutions, when the cached data expires, it has to be refreshed while the user waits. In environments that rely heavily on caching, such behavior has the potential to create thread pileups and other cascading failure scenarios. This plugin introduces a cache manager : when an expired âge is called, then it is directly served from the cache, and then the cache gets asynchronously refreshed.

This page demostrates a further step to make your confiuration files cached, in symfony way.
