The thing that has me puzzled is my business partner's Toshiba
notebook computer, a Satellite Pro 6100. He has Win XP on it, and then
added RH 9 in a dual-boot setup. Under XP, he had installed the Cygwin
environment.

He has a fairly large text file that he needs to sort. Using the
"sort" program under Cygwin on WinXP, he reports that the sort
completes in about half the time that the same sort on the same input
data runs under RH 9. He also reports similar time differences for
other compute and disk I/O processes.

I wouldn't think that window managers, etc. would have much to do with
this. It's the same hardware. I'm guessing that Cygwin did not
re-write the "sort" command, but is using the same Gnu sort and gcc
that Linux uses (circa minor version differences).

He found a BIOS setting that claims to force the CPU in high
performance mode at all times, and that helped narrow the speed
difference to where it is now.

Any ideas on what I can tell him to do to get Linux running almost as
fast as Win XP? Faster would be even better, of course. :-)

Ron.
