There are certain applications and DLLs that are incompatible with this form
of memory optimization. There are lots of safeguards built into both the
stuff in CPS 4.0 and in TScale to ferret 99% of those out. If one slips
through it will stop your application from working properly, so you will
find out pretty quickly if you have a problem or not. Just give it a try,
and if there is a problem turn off the memory optimization.

Thanks. I think I found the potential culprits. I have PS4.0 Enterprise,
so I guess I'll give memory management a try. Afew people responded to my
post the other day that it caused some problems and had to turn it off.

Hi Evan,
Since no one else answered your question, I will try. Go get Process
Explorer (free) from Sysinternals. Configure the lower pane to show DLLs,
and to highlight relocated DLLs. Now go browse (in the upper pane) through
the frequently used applications on your server. When you select a process
in the upper pane, the DLLs loaded by that process will show up in the lower
pane. Any DLL that is highlighted in yellow (relocated) will contribute to
excessive page file usage since there is a copy of the DLL in memory AND in
the page file for each instance of the program that calls that DLL. In other
words if you have an application that has 20 DLLs in yellow and 50 users you
have 1000 copies of that DLL in memory AND in the page file.
If this the case for you and you are running CPS 4.0, turn on the memory
management feature that Citrix licensed from RTO. If you are not on 4.0 yet
contact RTO for an evaluation of TScale.

4 gigs of RAM, 2003 SP1, PS4.0, Dual Xeon 3.6ghz processors and around 50
users logged in.
Physical free memory is 1.9gigs, and pagefile usage is 3gigs. Is that
normal?
