I think it's normal for an app to run full out to get something done when called upon. But today you find folk looking at graphs and wanting smooth lines or something else.
I have a Windows 2008 server running IIS.
I have noticed Weird regularly timed Spikes in CPU usage (100%) from svchost.exe (dhcpcore.dll wevtsvc.dll lmhsvc.dll)
What could this be?
