Wonder if the CPU frequency scaling is causing this issue. I had an
issue on a Dell machine at work where the box would run really slowly
if it got the slightest bit hot from being pushed too hard (usually
doing big Subversion commits or running sipp against a remote server).
The governor would take it down to the lowest frequency level to help
the machine cool down. This would even happen if I turned on the
performance governor. It wasn't a Linux issue at all, because people
who had the same hardware had the same problem on Windows.
