I don't have a clue what our requests/sec are (apart from what server-status provides) during any given time. The concurrent requests seem to peak out at about 120 split roughly 50/50 between the two major applications (which means about 35-45% are SSL) and the box doesn't have any issues and is (per vmstat -- forgot to mention it is a RHEL VM) 10-15% non-idle (user + sys + io wait = 10-15% usage). Currently, our proxy is performing some DNS lookups (DNS isn't on the box its self) do to how some of the access restrictions are done. I would assume that removing those would also lessen CPU usage. benji
