For what it's worth, that's why when we recently upgraded out UniVerse / Windows2003 Production server, I specifically said "don't get more than 4GB". To use more than that, with a 32-bit Windows platform, you need to use the /PAE and /3GB switches. I think you may also need to use Win2K3 Enterprise or DataCenter versions. I didn't want to make our UV server the first one in our network to be configured that way, so we 'stayed small'
If you want to use more than 4GB RAM with Windows, you really need to go to the Windows Server 64-bit editions, and you'd want to check the Availability Matrix to see which releases of UD are qualified.

What we are trying to do is be proactive to hopefully avoid a problem situation. Late last year we were forced to move to the latest version of the vendor software we use. Under the previous version, our registration process ran like a charm. It took a while for us to get to that plateau but once we had achieved it...life was good. This new software has a number of challenges that we've been able to address however, this coming month will be the first time we've used it for student registration. We only recently realized that because we are a Win2k3 32bit client that is *not* using SQL Server, we really can't take advantage of some of the advanced memory options available. Because of the way Windows manages memory, we effectively only have control of memory in the <4gig window. And to make matters worse, said 4gig window is sub-divided between user and kernel activities. So after monitoring system activities using RRDTOOL over a period of time, we realized that everything we are doing on the app server is crammed into <2.5gig...this is a 16gig box. We discovered that if our vendors' software had made use of the AWE API that allows for better memory management, we would be in a better position...but they don't and we're not. We have run registration simulations and have discovered approximately when registration will crash...but we doubt (and hope) we will ever reach that level of activity. You mentioned UD settings below. Would you mind sharing yours with us?

You would still need to make settings in Unidata to take advantage of the additional memory. Unless I'm getting the /3gig switch confused with the SQL settings. I'd also start with turning off hyper threading on the processors if you're using that just to see if it helps. Although I'm not sure if 7.1 has these kinds of problems or not.

We presently are running UD on a Windows Enterprise server (SP2) with 16gig of ram and 8 - 3gig processors. We have read through some MS Knowledge Base articles that suggest a possible performance increase if we use the /PAE and /3GB boot.ini switches. We were wondering whether anyone has deployed these settings before and if there were any problems that resulted...with either the OS or database. Does anyone have any suggestions regarding ways to increase UD performance levels in a Win2k3 environment?
