OK, *my* turn to ask detailed questions. :) How specifically is "I/O in
general" on Windows slower than, say, Linux or BSD? Remember, NTFS is a
journaling filesystem and is tunable, so you should compare Windows
(server??) I/O performance with, say, Linux, using properly tuned
journaling filesystems and identical (RAIDed) hardware. I think you'll
find that if you give a Windows performance engineer a chance to tune
the Windows server and a  Linux performance engineer a chance to tune
the Linux server, the two platforms will be competitive.

Come back to me in a couple of weeks; I'm taking a Windows internals
course and I expect to learn the Windows piece of that performance
engineering toolset. I've already got the Linux piece pretty well under
control, and I don't know anything about BSD.
