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. -- Cheers John -- spambait 1aaaaaaa at coco.merseine.nu Z1aaaaaaa at coco.merseine.nu Please do not reply off-list
