First up you should probably take a look at the CPU resources FAQ in the wiki.
This way you can at least confirm what Dreamhost is reporting regarding system resources. Not exactly sure what else to add, but if you’re using 400GB per month for that forum, and it only has 50 users/guests online at any one time, those users must be extremely busy, or your hosting a lot images such avatars and other media for your users.
On another forum I frequent, they have around 500 reg’d users, and on average they have about 30 users online at any one time, with it peaking around 60-70 users online in the evenings and the best it manages is around 15GB of transfer in a month.[/quote]
We have a vBulletin board sized similar to yours. We’ve had as much as 91 users online at any one time, and a fairly rapid growth rate in terms of message load (close to 1,000 in the last week or so, for example). We’ve never seen our resource usage climb to anything that isn’t acceptable here and performance is pretty good almost 24/7.
So, yes, I agree that the user in question must be doing something strange, such as running unusual mods or scripts, and/or providing videos or other huge downloads.
We consume more bandwidth than both of you combined, but that’s because of the Podcast version of our radio shows, so it’s not very resource intensive.
