[THIN] Re: Memory Usage

Tom,
 
At the moment we are using the old servers but will be replacing them
later this year.  We are currently looking into virtualisation for the
new servers so we are still to make decisions on hardware for them.
There is one new server in the new farm to help with the change over.  I
have been removing one server at a time from the old farm and then
rebuilding it to the new specs before moving the next bunch of users
across.  My problem with this is that I'm going to run out of servers
due the extra resource usage in the new farm!!
 
Our old servers are all dual processor Dell's with 2/4GB RAM.  I surmise
by your comments that you also didn't receive the improvements as
promised by the resellers.
 
Thanks for your feedback,
 
Geoff.

        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,
