It's a RAID5 SCSI system. I am well aware of how much hard drive activity
takes place on an e-mail system. I'm an experienced MS Exchange Server
admin. I know Disk I/O is not my bottleneck and RAM isn't an issue either.
I am well versed in checking these things out. They were the FIRST thing I
looked at. I'm not even using 1/3 of the RAM that the system has in it, so
paging isn't really an issue, exceot for the swapping of idle VxDs.

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.
