I guess I didn't know that Metaframe, IE and Notes ran on Linux. Silly
me!

Subject: [THIN] Even more performance monitoring
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.
