I am running GW 7.01 on a NW 6.5 sp 5 box.  On the poa I am always getting busy threads of 5:1 and files in the queues that number in the hundreds.  I have disabled the second processor already as per the NW tid's.  By the way the server is a Poweredge 2600 with a terabyte Raid and 4 gigs of ram connected to a 10/100/1000 Layer 3 switch.


Can someone point me to a suggestion?

THank you

How many mailboxes are on the Post Office? How many users are signed on at a time?

Hmmm...only 350 mailboxes?

Do you do routine message expiration and database purge? Or are users allowed to retain messages indefinitely?

Are all clients using Client/Server mode? No one is using Direct Connect, right?

I was in the process of setting up the weekly routines for expiration and database checks.  Currently the users maintain messages indefinitely.

Been outta town, so I'm behind on this one.

I suspect that, if the GroupWise System has been in existence for an extended period (e.g. a few years), that the issue is the indefinite retention of messages. How large are the OFFILES and OFMSG subdirectory structures? I imagine they're quite portly.

If so, then the sheer mass of information might be weighing down performance. I'll assume, since you have NetWare v6.5, that the filesystem involved is NSS and not FAT. You might try increasing RAM to enhance filesystem caching, but I suspect that unless RAM is so low that the machine is thrashing, any performance enhancement would be marginal.

If you want to continue on your current hardware, then you're going to have to establish and *enforce* some reasonable retention policies. You can't expect to let the message stores grow without limit and maintain performance on the current hardware.

If you insist on offering indefinite retention, then I'd look into establishing a new Post Office and starting to split your user population across the different POs. Since this is modern GroupWise (and NetWare), there are no licensing costs to do so, both are licensed on a per-user-seat basis, and the number of physical servers is not relevant (Redmond's warez would slap you with additional per-server charges). Your only cost is hardware/infrastructure.
