Gee, sounds like an OS issue to me! OS is what performs disk accesses to
data. Increased processor load (an maybe other things you did not see, like
Processor Queue Length) or slower disk access will definitely slow IMail.
Network access to remote disks cannot perform at the same speed as local
access.
