This plugin contains some extra storage engines that are currently missing from the symfony core - hopefully they'll be integrated at some point into the core and this plugin won't be needed.
Installing
The simplest way to install this plugin is to grab it from git. From the unix command prompt in the project root:
cd plugins
git clone git://github.com/dasher/sfStoragePerformancePlugin.git sfStoragePerformancePlugin
Provides
sfMongoDBCache by gregoire
sfMemcachedCache by myself
There's some really good information available on how to use these plugins on it's home page including how to implement Memcached that supports replication (master/slave, multi-master, etc) providing fault tolerance and memcached distribution.
Feel free to fork the git repo, add, expand - bring in other performance features for sf and we'll roll them up :)
