Thanks for the hint. This seems to make things a little better, but I'm still far away from 2.4 performances. I thought that anticipatory sched could be part of the problem, and booting with elevator=deadline does a little better... but using 2.4 is completely another thing. By the way, -a 512 vs -a 8 is a kernel "change" or an hdpam one?
