Topic: Punbb forum is hammering the server CPU
My forum has been slow for a while and I've finally gotten around to asking the host tech support for clues as to why. He says out of over 100 sites on the server mine is the 2nd most CPU hungry.
He copy and pasted the below queries and he says he suspects the problem maybe that I have several large tables. This could make sense because there are some topics on my forum that have over 5000 replies and are steadily growing every day. Those large topics have been the very slowest to open.
Actually, I've now closed those large topics and moved them to a hidden admin forum so that they can't be access. That resulted in a much faster forum BUT it has gone slow again this morning.
