Problem:

My Windows Server 2003 Terminal Server is a Dell PowerEdge 350 (700mhz
clock) and seems to have a bottleneck. I have about 6 users connecting to
the T/S, each of which complains of very slow response. The server has 1gb
of ram and seldom consumes more than 700mb.





What I've done to identify the problem:

I've set up the Performance Monitor to watch several counters. I've found
two scenarios to be quite common, particularly #2.



Scenario #1 happens on occasion - According to Microsoft, "To determine
whether a processor bottleneck exists due to high levels of demand for
processor time, check the value of the System\Processor Queue Length
counter. A queue of two or more items indicates a bottleneck." My Processor
Queue is typically 7-8, or up to four times the expected rate. However, the
% Processor Time counter only shows an average of about 15%. I would think
that if there were this many queued processes that the processor would be
running at 100% to work the queue.



I've also found that % Interrupt Time and Server Work Queue counters are
very low.





Scenario #2 happens very frequently - The % Processor Time counter shows
100% usage. Pages/Sec and Page Faults/Sec seem to track together and often
exceed 80% during the % Processor Time high usage periods. The Average Disk
Queue Length is only 0.062.



Summary

While the Terminal Server environment loves fast CPU's I'm not yet convinced
that a faster CPU is the answer. I'm more wondering if there is another
problem that I haven't detected. I would really appreciate anyone's input.
Thanks.
