My customers log on to our terminal servers from the internet, we experience much hickups when there are more then 10 users logged on. I have no clue on the reason of this. We use Appsense for performance monitoring.
The server is a 2Ghz 2Core Xeon. 4GB memory, 80GB Disk. The only process that i see tha may cause the problem is Windows Defender. and the Local session Manager, these are the only spikes i see on the task manager
