I dunno, but I went looking on web diagnostic sites and the consensus is clear, its the host and server size, we have more users than the host can handle, a "heavy site".
No don't think it would be the answer. There are a ton of things to do that help a little. vBulletin loads with a lot of defaults that are nice but only work with small sites. I've sent Juan a whole list of things they suggest to get the speed back up.
Why is this site so buggy and slow these days. Lagging like crazy on me and I tried 3 other browsers and still the site is very slow. Crap wrong forum topic. Please move this one to the correct place my bad
