- SCSI Hard Drives. No partitioning. Defrag by Diskeeper.
as we have said here many times, partitions:
** OS + apps
** dedicated swap
** dedicated spool/
** mailbox storage
** and if you were a heavy webmail, a partition for webmail workspace
Turn off all logging except SMTP (you gave stats for POP, so you must be logging POP, turn it off). Turn on non-STMP logging for debugging.
If we decide you're suffering from fragmentation, then think about a Partition Magic to setup the partitions to what we think here is "best practice"
- Mailboxes are using 4GB of total disk space. only 120 users take advantage of our "masochistic generosity" and use more than 10MB.
ok, but if they are on that 50-post/day mailing list and heavy mail users, then there will be lot of access to their mbx's in a very short time.
- The spool contains between 500 and 800 files on any given day, with no files older than 1 week.
not too bad
what about your defragging practice?
With everything dumped in on partition, fragmentation could be horrendous.
- When processor utilization goes to 100%, the primary culprit is SMTPD
receiving mail, and applying rules, etc
(10% to 40%) and between 10 and 20 SMTP processes (each between 0% and 20%). The 100% processor is most often triggered by a 120 user mailing list that receives about 50 posts per day.
ok, that matches up, delivering to 120 users is a big dollop, but really, not very much for your machine.
and the SMTP would be delivering to the 120 list recipients. If a bunch of those were local, then that would be a big shot of local disk access to deliver to the mbx files. and if the partition was horribly fragmented....
- can you give more explicate instructions on the looping batch file.
