Barry,
I was able to get through some problems on XP by upping the Java heap as you
did and getting rid of a results tree reports that I saw takes up a lot of
memory, and can now run 50 threads without a problems.
I have also noticed that in XPs task manager that the number of handles keeps
going up on the performance tab. In the middle of one run the handle count was
up over 8000, and was increasing over time. With 50 threads, the count would go
down 10, up 10, up 2, up 2, up 4..., and would always trend higher in the long
run. Maybe once the immediate memory problem is avoided there is another issue
causing this to happen?

Subject: Is JMeter using too much memory?
I have a script that exercises a servlet-based application (running on
Tomcat). I would like to do some massive multi-user tests, but on Windows
2000, just running 35 threads runs the machine out of memory. I do have
-Xmx384m added in the jmeter.bat file, otherwise the JVM runs out of memory.
Should it really take that much memory (this machine is a dual PIII with 512M
and not really doing much else)? The script has a cookie manager and an
aggregate reporter, and all the rest is just html samples recorded using JMeter
proxy. This machine is Win2k, JMeter 1.8 J2SDK 1.4
The same script pretty much maxed out the CPU on a Dual P4 1.7G at 20 threads
under RedHat 8. Don't remember how much memory was used, but it was a lot. Am
I doing something wrong or is 20 threads about all I can do per machine with
JMeter?
I can send the script (it's about 37K zipped) if that would help.
Thanks,
Barry Roberts
