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.
