Kernel Upgrade Fun

A few days ago I did a kernel upgrade from 2.6.24 to 2.6.32.1. Surprisingly the load on the server has dropped slightly. The server is generally under minimal load, just the way I like it so a drop is particularly surprising. It was restarted just a few weeks prior, so I don’t think the restart had an impact on load. Unscientifically it appears the box is under the same level of usage as prior to the upgrade. The two spikes that delimit the restart are due to some log processing.
