We have a dual CPU Win 2K system running CFMX and IIS 5 with a gig of RAM. During the busy time of day, the processors are still loafing at about 10% activity as shown on Task Manager Performance tab. Task Manager shows lots of Page Faults for the jrun process (the guts of CFMX), about 100 per second, but these don't translate into very many disk accesses, so it's not clear what 'page fault' really means here. An odd thing that occurs, and I expect that it occurs with other users of CFMX, is that occasionally the CPU utilization kicks up by about 50% on both processors, to maybe 60% utilization. It will stay at this level for a few minutes, then drop back down. Does anyone know what this is, and if it is normal? I would imagine that it is some sort of cleanup process, but disk accesses for jrun stay at zero during most of this 'intense activity', just rarely making a jump. I am trying to understand what this is, and if we're about right. Our CF pages per second are about 8 during the busy time, and our times per page are OK, so I am not too worried.
If any of you have some real insight into this, it will make me feel better.
