bbpress uses so few queries that caching has got to be a low priority, especially when the point of a forum is to have very dynamic updates customised for the logged in member – it’s very different than a wordpress environment

as long as you have the mysql cache turned on, it should be very responsive – just look at the main wordpress support forum – eaccelerator would take care of caching the php opcode and that can’t be too far behind a static page

the bonus is that on an active forum, everything will be very dynamic as it happens…
