Hi Mike, We run our Dev and Test UniVerse 10.2.10 servers in a virtualized environment. The ESX servers are connected to a EMC SAN via fibre channel.
We have noticed a bit of slow down in the virtual servers at odd times as well. Our user load on these servers is small (10 - 15 users) but they can be running large processes during tests. The ESX servers that host the UniVerse VM also host a lot of other VMs (such as BizTalk servers, SQL servers, file and print servers and Web / share point servers). Any above-the-norm activity on any of these can cause a slow down on the other VM as resource contention kicks in. Do your virtual host servers use SAN storage? Also, what other VM are hosted on the hardware and what are their activity patterns like? I have found that if one VM is doing a lot of disk I/O, it can take the ESX server a minute or so to balance the load to give the other VM a chance.

Without us taking any action the system begins responding normally again and we usually make it through that day without issue. We typically have around 85 users on the system at one time sometimes that gets up closer to 95 or 100 but not often. I have noticed certain processes that definitely cause the issue like running winmsd from the command line or renaming a directory on the server. Since I know these processes cause the issue I don't do that during the day. Obviously there are other processes that also can cause issues for us. We have worked with our vendor and Rocket and the latest we've gotten from them is that our server is under-resourced. While that very well could be true, we want to do a little more research first and reach out to other Windows/UniVerse users to see what hardware they are running and if anyone is in a virtualized environment. Any help we can get would be appreciated.
