Did you run the RH-6.2 stuff on exactly the same hardware (including
same disks?)
What about the disks, are they running with DMA enabled?
Over here our mailservers used to be IBM PC's with Fujitsu Harddrives.
After some time of operation they started to slow down and load started
to increase. They even did not respond to ssh sometimes. In the end I
saw that those disks failed under the heavy load of the mailserver and I
replaced them with other disks. We have hundreds of the same disks in
windows desktop PC's with no problem. Linux just pushes the hardware
more.
