My company uses 3 terminal servers and 2 fileservers in our network to deliver hosted desktops to our customers. Last month we are experiencing performance isseus. We are investigating this issues and the first thing that came out was the memory, we upgraded the memory, this solved a bit of the problem but still when there are more then 7 users logged on there getting performance issues. The second thing we did was implementing Appsense to manage spikes on the cpu and memory. This improved everything, we can now let 12 users on the servers. Still an incredible low number of users.
The biggest complaint i get is that the users have slow file access. When i look to the network card of the server it sais that its not using more then 1% and the fileserver is idle. We use Distributed file System on our 2 windows 2003 file servers. The terminal server are windows 2008. We have also one windows 2003 server and that is not experiencing this problem. It looks like a problem with DFS from my point of view. Anyone have an idea of the possible cause of this problem?
