-------------------------------------------------------Thanks James.  

When using exmon, what fields would show IO usage?  There is obviously
bytes in and bytes out but what about packets or operations?  Our disk
is being slammed by IO and I sometimes wonder is it really the amount of
data being transferred or could it be lots of searches, indexing, etc
where people aren't necessarily transferring large attachments but are
just doing a lot of manipulation of e-mail.  For example, which would
make more IO - copying one large file from one disk to another or
thousands of small files equal to the large file.  

Users on the top of the list in bytes in and bytes out are always
changing.  I noticed that users in the top of the list of packets and
operations are usually the same bunch.

Thanks again.

-------------------------------------------------------Could be several
reasons

1. DSACCESS related issues. Turn up diagnostic logging.

2. Sites and services are misconfigured and Exchange is using a remote
GC for lookups

3. You are incurring additional IO for some reason. See if there is some
process running; some large mail sent etc. Run perform and check your
physical disk avg disk sec reads and avg disk sec write. If you're over
50ms sustained you need to investigate. Also can look into using exmon
to see if a particular user is incurring the additional IO

4. Turn up diagnostic logging msexchangetransport

5. Run Exchange best practice analyzer

I'm facing a problem related to a very large amount of messages stuck in

Server performance to slow down and delaying the delivery of my user
