Re: Buddypress 1.5 using too much resource??
That just prompted me to search my inbox for the problem so this is what I wrote a few months ago when I was having that problem :
====
If you’re using pretty permalinks then you have to start it with a numeric identifier like %post_id% or %hour% anything with a number in.
%postname% on its own is fine for small sites but wordpress has a bug which sends it into database mental town for big sites.
Just putting %post_id% in and updating all the links has reduced me from 1300queries to 37.

Maybe even WP3 has solved the problem, to be honest, I’m one of the people who forgets about things the minute they get sorted.
