careful here.. if you have 2003 advanced server, you get WSRSM which is
Microsofts built in technology to process priority scheduling..which I
understand is possible to disable...also, win2k3 also includes the
improvements in 'copy on write' DLL management stuff..
I'm not an expert and I have only used Aurema's armtech on a win2k server and
the improvements were absolutely gob smacking!
the problem here is that there don't appear to be any bottlenecks? no
processes are doing any hammering...
I would look for any numbers that look extreme.. context switches etc.. guess
guess guess

with that much mem being taken up by the accounting app per user alone, it
might be worthwhile looking into something like AppSense? I seem to recall
that (i think) Mr Ron Roggly ( :) ) posted there was a util you could run on
your server, you send it to them and they tell you how much the program would
help you - but I cant find the url now :(
On the other hand, it could possibly be the hyperthreading, isnt it supposed
to take quite a hard performance hit (comparatively) if it guesses whats going
on wrong?
(More straws please! :) )

We have a new 2003 TS with under 50 users but we are having a bit of a
difficult time locating the source of the overall system slowdowns. Is
there a way to pinpoint the exact cause of a problem slowdown? The
programs used on the TS are office 2003, QBooks and other accounting
programs (which is the bulk - each session consuming 60-130mb for the
accounting program @ each user). From what we see, the network
bandwidth is non-existent, drive speed/access is low but the CPU spikes
randomly on this dual xeon 3ghz on a dell PE6650. RAM is 3g,
hyperthread enabled, RAID 1/5, all data on server and apps loaded on TS.
We are just about to contact a third party to pin this down or MS PSS
for I feel me are missing something here - just not sure what. We are
running the MS service perf advisor now to see if we see anything. One
of our techs did check the PTE and recently added the /3g switch for
checking if it helps.
