[THIN] Re: Memory Usage

Hi Geoff
Post upgrade blues eh?....promises not delivered. Results and
performance improvements hardly recognisable. I know the feeling. What
hardware are you running(processors etc). did new servers go in with the
upgrade?   Your previous farm must have been a few years old?
 
I can't give you any suggestions on optimising memory usage. Explorer
looks hig compare to my environment ps4 w2k3
 
these are my averages for the processes you mention 
explorer 9MB
wfshell 4.5 - 6mb
crss 4mb 
winlogon 4mb

        Hi All, 

        We have been running a small Citrix farm with Windows 2000 SP3
and Metaframe XP FR3.  Finally we are making the conversion to Windows
2003 SP1 and Presentation Server 4.0.  After hearing all of the hype
from both Microsoft and Citrix about their relevant upgrades being able
to increase the number of users we should be able to now get on each
server I was looking forward to the change.

        However, to say I am disappointed with the memory usage results
of the upgrade is an understatement.  I now find that I am not even
getting as many users on each server let alone an increase of 25% or
more as stated by some sources.  We are running the same applications
(including versions) on the new setup as we were previously.  I have
turned on memory optimization which may have made a little improvement
to the applications, but the problem seems to be related to the new
operating system and the new version of Citrix themselves not the
applications.

        On an old server I would get 40 users consuming only 2.5 GB RAM,
but on the new servers I get only 30 users and I'm already consuming
more than 3 GB RAM.  It appears that the main consumers of all the RAM
are operating system/Citrix process rather than the applications.  For
example, on the old server Explorer.exe consumes around 5MB and on the
new version around 15MB.  Crss.exe was 2MB and is now 5MB, winlogon.exe
was 3MB and is now 6MB, wfshell was 3MB and is now 5.5MB,
