Have you tweaked Windows to the max in regards to Memory settings etc,
for example have you made any boot.ini modifications such as the 3GB
boot switch.
No as we did not think it needed it, the machine is not running out of
ram.
How do your clients connect to exchange, local Lan, Remote via RPC over
the internet, Modes (Cached or Not), how big are their mailboxes, how
many items in inbox etc. They are way to many factors to list.
Local lan, Outlook Fat Client.
In short I've handled Just as many if not many more users on a single
raid 5 setup in exchange 2003 with no performance issues.
How many raid cards do you have, makes modules setup etc. Junky raid
cards will also eat up your cpu, since they rely on software etc.
Two raid cards, Smart Array 642. No multi-path software installed.

Subject: Exchange 2003 Upgrade (sluggish performance)
Hello Gents, we have recently upgraded out Exchange 2003 configuration
to boost performance as it was a bit sluggish. Bellow is what we went
from and what we ended up with. We basically added a disk array to an HP
ML-350 and a bunch of disks. Afterwards we moved mailboxes and log files
accordingly. I am pretty sure we did it right however performance is
still lagging (badly at times). Users are complaining their Outlook is
taking up to one minute to change folders. Any help or feedback would as
always be appreciated. Thanks In Advance--Aristotle Zoulas
Went From:
OS+Exchange Install+Page File <<Mirrored Drives-C-drive>>
Storage Group #1 with multiple Stores+Public Folders, all Transaction
Logs--<<Single RAID 5 Volume>>
We had performance issues across the board. Long Average Disk Queue
length.
Went To:
OS+Exchange Install+Page File <<Mirrored Drives-C-drive-Internal ARRAY>>
Storage Group #1 (Executive Store), Public Folder Store-<<RAID 5, three
spindles, -- D-drive-Internal ARRAY>>
Storage Group #2 (InfoWorkers Store + Managers Store)--<< RAID 5, three
spindles --E-Drive-External ARRAY>>
Transaction Logs (Storage Group 1)--<<Mirrored Drives-F-Drive-External
ARRAY >>
Transaction Logs (Storage Group 2)--<<Mirrored Drives-G-Drive-External
ARRAY >>
All mailboxes were moved to new locations using "Exchange Tasks" move
mailbox method in batches.
The Executive Store is approx 20GB EDB+ 5GB STM , the Manager store is
approx 30GB EDB+2GB STM, and the Infoworker Store is 3GB EDB+1GB STM.
What we are seeing:
Overall Slow Performance, especially for Storage Group #2. Still
have relatively long Average Disk Queue length.
It seems the performance is worse than in the single RAID 5
configuration (IMPOSSIBLE)
Did we do anything wrong? Could we be doing anything better?
The machine is an HP ML-350 G3, Dual 2.8, 4GM Ram, with External Raid
Array MSA500 G1.
