Slowness Exchange 2003 Standard

Posted on 2009-04-28

We are having slowness related to our exchange 2003 server when we add people to a calendar meeting, showing the free and busy time for a user.

Or if we try to sort on From: in the Inbox, the Outlook 2007 client will freeze for 5 - 15 Seconds, and then will come back and show the sort.

Additionally while writing an e-mail, the typing in the subject section will simply stop, then 5 - 15 seconds later any characters that were typed will fill in.  Often times an e-mail will arrive directly after the freeze.

I dont believe this is a network issue, I am directly connected to the Core Switch that the Exchange server is connected to.

We have E-Mail archiving appliance running to remove mail from the mailboxes, but still show a pointer to the archived mail, I should only have 60Days worth of mail in my e-mail box.

This is consistent with e-mail boxes that are much smaller also.

I have 8 information stores on the server, to divide the mail boxes across stores.

The server is an HP DL380 G4, AMD Opteron 280 Processor, 2.41Ghz, with 3 Gig Ram, I am using the /fastdetect /3GB /USERVA=3030 settings in the .ini file.

The OS is Windows 2003 Ent R2 SP2, and Exchange is 2003 Version 6.5 Build 7638.2 Service Pack 2.

We have Message Tracking enabled and enable subject logging and display enabled.

We also use Outlook Anywhere and Mobile Phone access extensively.

Any suggestions to make the server more available would be appreciated

    i think the server is facing the disk bottle neck.

    try to get in touch with Hp for to check the condition of disk. also try running EXTRA tool on the server. you could download this tool from , select the second tool to download. also run ExBPA and let me know if find any error messages.

    I looked into the hardware first, I started the HP System Manger and found I did not have any issues reported but the HP Monitoring tool.

    I ran the ExTRA tool and found that there is significant I/O activity, additionally, there is a high number of logons per mailbox 6.44 per mailbox.

    There is also a high user activity level of 1.386 operations per sec / per user.

    So the recommendation according to the tool is to add another e-mail server.

    So is this as simple as building a new Exchange server into the domain, and then using the migration tool to move mailboxes to an additional server?

    I would expect to move all users of specific information stores to the new server, I mentioned that I have 8 information stores on this server.

    I really did not think that this server was over utilized since I heard that there are several hundreds of mailboxes on a single server, we have <100 mailboxes on this server, and we are archiving to a different server to keep the data light on the server.

    This really does not make complete sense to me.

    sometimes it happens that the hardware manufactured is not upto mark.

    i have seen many cases were we need to change the hard disk.

    so i would recommended to decrease the load on the server and then you could the moniter the activity on both the servers. if still you face the same issue then it is matter of concern.
