BuddyPress.org

I too am currently evaluating BuddyPress, for use in a University (so in 5 years we’ll be looking @ roughly 30.000 blogs). My experience so far is that BP needs a lot of queries to load the page.

Has anyone got any experience on finetuning linux, apache php and mysql for a site like this (memory, caching, network etc)? Needless to say i’ll be running a dedicated machine for this site (and got root access).

I’d love some configuration recommendations, specifically on proxy/caching strategies, backup and clustering.
