1. You can clamp memory-use using 3rd part tools (AppSense Performance
Manager, WMSoftware Revelos) this can have a -ve impact on the app's
performance tho'. Best to test with the apps.
2. Store cache files local to the OS the user is running: not on a
network drive - you'll get much better performance.

Subject: [THIN] Question on custom Java Application
Hi,
We have a custom application that basically is a Website using loads of Java
to open Manuals and PDF's and navigate through them.
I have two questions ?
1. The Java.exe and Javaw.exe processes can consume up to 180 Mb on the
server which I think can be starving other processes on the server. Can this
process be tuned or clamped to a max value and is their implications doing
this?
2. We store the Cache directory for this application on a network
share, any time a user uses this application up to 50 files can be open.
Would there be any implications moving these files to the local drive of the
server. Its to get round a configuration issue if users use XenApp from home
or on the road if their normal desktop is Vista / W7.
Any insights would be greatly appreciated.
Thanks
Ronnie
