At what speed (pace) does your shortcut task run? (Exchange Environment)
Hello,
My Exchange environment is:
Exchange 2003 Enterprise
2,200 users spread over 2 servers in 33 Private Stores in 7 Storage Groups.
Total Mailbox sizes = 847GB
Just wondering how fast your shortcutting tasks go. When looking at the log details (if you have full logging on) you can judge how fast it is working by roughly how many shortcuts it creates in a second.
***Currently, my speed is roughly 1 shortcutted email every 3 to 4 seconds.
Wondering if others see similar results. I realize that our environments will not be exactly the same, so this is just informational.

Hope you'll figure this out.
Regars, Jochen.

I think it is slow as well.
Our entire exchange org and hardware systems are new. The users were migrated in about 6 months ago. Our disk system is gig Fiber to a SAN, and the disks were carved out in a way to optimze read/write times (so many heads, platters per partition).
Perfmon on our EX server shows low averages for disk, processor and memory. On our exchange server the disk queues are always showing something, like an average of 4 to 10 (avg. disk queue length).
thanks again

The speed of a shortcut task requires some good disk performance, since every message is "touched". I would think "Exchange disk performance", but EMC told me that this is also true for the "EX disk performance".
Best regards, Jochen.

Thanks for the reply again.
We ARE using RIM's Blackberry Enterprise Server, and recently we opened a T-support case regarding users receiving RED X's and their devices not staying in sync with their mailbox. They had us log many perfmon items to a binary file and their conclusion was pointing to latencies in RPC related to disk.
My solution, was to separate my user base into 15 assigned agents instead of letting the BES assign it's default 1 per server. It was capable of auto-assigning up to 5, but it was choosing to stay at one per server. after splitting my users into assigned agents, the performance and quality of service shot up dramatically. This is not a recommended practice, but they conceeded that it gave us more "active arms" to process our user's mailboxes. It has been working great for 2 months+. Our BES server is able to handle the extra memory requirements of this setting.
Sorry to get off topic of Shortcutting. But this initial question was related to our internal investigations for latency. I'm concerned that it is also affecting the speed at which we can shortcut.
I believe we are shortcutting at a pace SLOWER then the actual activity of our mail system. Put another way, more mail is being generated in mailboxes than we are shortcutting. Losing the battle so to speak.
thanks again.

One customer I know (with BES) bought a new storage with increased performance, another one (with BES) could move the mailboxes evenly over the information stores and therefore the spindles.
I see your problem. Well you have archived the items faster than you shortcut (that's positive)! Have you multiple shortcut tasks running already? How "quite" are your weekends?!
Well, good luck in anyway!
Jochen.

Regarding your comment: "Well you have archived the items faster than you shortcut (that's positive)! " , i think you mis-understood. The general day to day activities of our users is generating more new emails, then our shortcut tasks are able to shortcut. Essentially, our .edb files are growing faster than we can shrink them. (we journal messages so we don't need to archive. We DID migrate about 700gigs of mailbox data from another Organization 8 months ago, but have archived almost all of it.)
We were originally restricted to running tasks outside of business hours, but that was because we were archiving, and the changes it made to Cached Mode Outlook users saturated all of our WAN links. Now that we are only shortcutting, that restriction has been relaxed. Now i'm running multiple shortcut tasks on Storage Groups most in need of space.
Our weekends are about 50% load, and the tasks do run a bit faster. Looking forward to this weekend.
We actually performed a VERY good test today. We added an empty exchange server to our Organization, and moved a user with a large mailbox to that server. we ran shortcutting and it shortcutted 948MB in 5 minutes! This verified our results from Perfmon, that disk latency is playing a very big part in causing us headaches for BES, as well as Archiving services.
Thanks for the communications,
