Hi,
I do not believe it is a fragmentation issue. I can access the files
directly in no time.
By the way we are using IMail 6.0.3.
Another thing, when IMAP is executing a request, the processor usage goes to
100% and hogs the entire system.

Remember, the first several passes of defragmentation can be excrutiatingly
slow and long on a badly fragmented partition (10's of 1000's of file
fragments and free space fragments), but later defragmenations will be
faster. It will be quicker to backup the parition, reformat the partition,
and restore, but still run the defragmenter continuously as prevention.
Your partitioning strategy is key: With a one disk system, I do
c: system progs (intall absolutely nothing in here, if avoidable)
d: swap (3 times the size of physical memory)
e: all non-system programs
f: data ( being your mailboxes, so this is your defragmenting horror and
target )
At which point, good old NT can't count above 4 partitions per physical
drive. This is "innovation".
If the IMAP performance is still slow, then you'll have to take a look at
parameters at the application level.
