Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

When the server is running slowly, anything I type in any text entry box comes in out of order. For example, IPCONFIG might become IPFIGCON.

Basically, our Windows Server 2003 R2 x64 Terminal Server is getting incredibly slow at times even under 1-2 user load. The server is at less than 10% ram and CPU usage. I am thinking this is a hard disk bottleneck of some sort but I also am curious as to why I'm getting bottlenecks with only 2 users logged in not doing anything too intensive.

Has anyone seen anything similar? I am looking for people who have experienced a slowness problem causing out of sequence text input, and would like to hear about how they resolved the problem. Not really looking for a guide of how to use disk queue length performance counters, but all input is always appreciated :)

I always vote and accept when possible!

I've seen this. I've typed stuff and had it show up 10 seconds later. –  Nixphoe Jun 24 '11 at 17:50
    
Do you use this server for any other processes? Do you connect to it through the internet or locally? –  Nixphoe Jun 24 '11 at 17:52
    
the server is on a machine that also hosts VM's, we are thinking some of the other VM's might be causing this garbled input due to IO / disk usage as that is the only thing that makes sense. –  Az. Jun 24 '11 at 22:22
    
Detailed performance information/counters may already be available depending on the hypervisor used (hint: it may help to identify the hypervisor). –  user48838 Jun 25 '11 at 8:52
