The only type of control panel I've got on my server for checking server load is vBulletin, and today it's been reporting a load of 9-11. Using the top command via ssh the CPU load is not going above 70% though, so why is a load of 9-11 reported by vBulletin? I know that it is the cgi proxy that's causing any extra load because the number of page hits have quadroupled over night.
