On my Windows 7 machine (build 7100, x64, Dell XPS M1710 laptop), I'm getting horrible performance after chrome crashes. I kill the chrome process from the Resource Monitor, but after that perfmon.exe itself is shown as taking about 50% of the CPU (52.31% right now).

Quitting Performance Monitor, then starting it again, shows perfmon starting out with a reasonable CPU, but it quickly (ten seconds) shoots right back up.

Suggestions? So far a reboot seems to be the only way to solve the problem. I'm assuming that the perfmon issue is just a symptom of the real problem.

(Update, much later: this never got resolved. I'm not seeing the problem in the RTM Windows 7 + latest Chrome. Yes, it was a core 2 duo, so presumably Chrome was running full blast on one CPU.)

This question came from our site for system and network administrators.

Why do I have the sneaky feeling this is a multi-core machine? Specifically, one with two cores? Could you please indicate how many cores you have? – Avery Payne Aug 2 '09 at 22:58
At the risk that this question may not be revisited - I believe Avery's thought is that on a two processor machine, one processor is at 100% utilization, and the other is idle, reporting 50% utilization. – JohnW Aug 4 '09 at 0:19

Perfmon.exe -> try finishing the proces and you will see what happend. Perfmon = PERF (Performance) MON (Monitor) Actually the logic name for the Resource Monitor process it could be "Resmon"... but we know microsoft.

Un saludo! I hope that this helps you.
