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,
