A quick check showed IE 6 using anywhere from 2MB to 23MB of RAM and
proc utilization at 0% with spikes to 30% on one of my Citrix servers.
Occasionally IE (and some other apps) will use 100% of my processors. I
use PowerFuse, which immediately throttles that back to 10% so that
other sessions aren't affected. I think TScale and Appsense also do
something similar.
Good luck,
R

Next he will tell you to use WINE to emulate windows in Linux. Back on
topic, every time I have checked IE 6 has been more of a resource pig
than 5.5.

~}It's taken me almost a month, generated about 1GB in logs, and
probably
~}took almost 60hrs. I've correlated almost all the "hangs" on my main
~}server to which applications were running and how (CPU, RAM) the
~}applications were running. What I found is something we all knew:
~}Internet Explorer and Lotus Notes are two big apps. Each app has gone
~}above 250% CPU. If I read this corrrectly, it means that they were
~}taking
~}up the resources of 2.5 CPUs of my quad processor server. That's a
lot
~}of
~}processing. They have also taken over 1GB in RAM, at times. These
~}are
~}per instance metrics. In other words, a when the CPU or RAM spiked,
it
~}was
~}in a single session. Someone else could have been using the same apps
~}with
~}minimal performance hit to the server.
~}
~}I've also learned that when you tell perfmon to monitor ALL threads,
~}prepare yourself for a lot of work. Huge files, tons of entries...You
~}wouldn't believe what my screen looked like. There were so many lines
~}on
~}the screen that it took about 3 seconds to refresh every time I
deleted
~}an
~}item from the graph.
~}
~}My next step is to convince mgmt to let me upgrade to IE6 and Notes
~}6..maybe even Windows 2003.
