Anybody who is running vbulletin is at some point going to need to get threads and posts cached. I have been playing around with the system and it is useless at keeping resource usage down so I do reccomend you cache at least posts and threads if you are running vbulletin. I am very interested in seeing live forums that cache posts in vbulletin. Do you cache threads and posts in vbulletin? If you do cache them can you post before and after resource stats. Thanks.
