Re: Caching in bbPress?
From what I remember the inbuilt cache in bbPress (when turned on) is just an optimised list of topics, posts, forums etc. Not entire pages of html.
MySQL caching is definitely a good idea. I’ve had trouble with eAccelerator in the past though – it used to munge multi-dimensional session data (can’t say if that’s still the case, or if it is a problem for bbPress).
