Is you DISK SCSI? if not, it should be. If not, you can patch NT to take
advantage of UDMA 66 on you EIDE drives? Mail Servers use a lot of DISK I/O.
If you disks are CPU bound (IDE) then this could be a large part of your
problem. Take a look at the task manager and enble the "Show Kernel Times"
If the the red part of the CPU usage ever gets above 10%, IDE Disk I/O is
probably your problem. This gets even worse if your system starts to page
the kernel or Imail to VM.
