Re: [PLUG] recompiling a kernel for performance

Your links are to 2.6 kernel items so I presume 2.3 is a typo?

Do your cluster tools allow you to measure the performance of specific nodes? If
so, you might be able to update a few systems and look at the post-simulation
stats to compare the performance of the updated nodes to the "vanilla" nodes.
