Hi Pavlo,
Interesting application mix.
We can probably exclude MSoffice (with Access) and Acrobat and IE. Great Plains
is probably okay (except for disabling oplocks). I gues Staffright and
Accuterm97 would likely be the most promising possibilities but it's basically
a case of finding out what applications (if any) are showing excesive pagefault
activity.
Paging is a normal housekeeping function and the (Microsoft) operating system
will page long term inactive processes (and their DLLs) out of memory
regardless of the amount of free memory. The more processes you have, and the
bigger their memory footprint, the more paging you will see.
It doesn't matter how fast your CPU and memory are if the limiting factor is
paging to a much slower disk subsystem. This is why products like TScale etc
are so effective. By allowing most DLLs to be used as shared code, the
per-process memory footprint is greatly reduced, as is the amount of paging.
Anyway, "destructive" paging (system gets so slow its unuseable!) or swapping
generally only occurs when you've run out of physical memory so what you're
seeing there is kind of unusual. I'd normally look at everything memory-wise
(in perfmon) just to try and get a handle on what's going on.
But initially you're looking for an application or system process with a very
high fault rate. Could be any number of things from there, but that's a start.
regards,
Rick

Hi Rick,
Thanks for your help. I'll remove Page Swaps from load evaluator.
Here is more info about my setup:
30-40 users per server daytime.
Published Applications:
MS Office 2000
Adobe Acrobar 6 (both Reader and full package)
Microsoft (Great Plains) Dynamics (SQL client)
Fundvision (SQL client)
FRx reporting tools for Dynamics
StaffRight (old DBase time-management DB)
Accuterm97 (terminal programm for telnet to old Patient inf system)
New Patient Inf System (SQL client custom app)
Some Access DBs
IE 6 SP1
Servers are W2K Server SP4 with hotfixes:
822428
823980
824946
147222
MF XP FR3 with hotfix:
XE103W2K082
I've been running taskmgr with Memory usage and VM size but not the Page
Faults. Is the process in question suppose to show high Page Faults value?
I tried perfmon but there are so many processes that I would like to narrow
it before going perfmon way if possible.
Thanks,
Pavlo Ignatusha
