i moved away from Red Hat 2.4x kernels as they have an annoying tendency to swap instead of giving back cache. I moved to Centos-4 and i have vm.swappiness to zero and am using at most 144K of swap across 5 machines.
I should have mentioned that every time I compare a 2.6 kernel with RHL 7.3 on this test: hdparm -t /dev/hda
RHL is always faster. I was also running some other tests involving bonnie{,++} where RHL was still looking good, then Google interevened.
Known problem.
It was a year or so ago, maybe it's fixed.
