Subject Re: unable to set MaxPermSize past 128MB

well because this is for an 15K member organization, and that is a MAJOR
change.  I'm in charge of the web project, not the hardware, and as much as
I've fought that battle, the best I've gotten was virtualization still on a
32-bit OS.  I ordered 2 new 2K8 64b systems (still virtualized :: stroke
::) but they should take care of all the users.  If I had my way it'd be
different, but you know how corporate world is.  Just like the military....
hurry up and wait.  :)

I DID manage to get everything running mostly optimally.  Here's what I did:

in the environment variables I set JAVA_OPTS = -XX:MaxPermSize=256m
-Xms=256M -Xmx=1536M.  Now Tomcat runs FAST and with about 3000 users, it's
still blazing along using about 150MB on each of the 4 boxes.  Much better
than 500MB per box, with 1500 users.  If it needs more ram, I change the
variables and bounce the TC Server.  No biggie.

Thanks again Charles!
