unbelievable test results
Hi
I am running jmeter in command line mode on 3 linux machines(2Gb RAM and
dual processor). Thes e three instances of jmeter are hitting one jboss
server. I have configured jmeter for 9000(3000 x 3) threads. server is stil
running in very good condition and is fulfilling the requests in very good
time.
I cant believe this. What can be the reason? it is urgent. Please reply ASAP
NOTE:jmeter is alloted with 1024MB of memory.
Thanks,
Abhishek

Dood!
3000 threads is totally insane, there has to be something going wrong.
Step one - find out how many threads the jvm is actually using!
Step two - find out (as suggested) if the responses are real or they are errors being sent back - or errors thrown because JMeter is not connecting etc.
Step three - Just scheduling 3000 threads should kill the cpu. So - what level of cpu use and network traffic are you getting.
Oh - you have not actually said what you are asking JBoss to do - JMS, HTTP, etc etc. That would help to know :-) [unless I missed it]
Cheers

Just tried it with 10 threads on my Linux box -- it consumes ~ 450MB,
and 12% cpu.
Probably depends a lot on what you are doing, delay times etc.
Abhishek: I would add a request tree listener and take a close look at
the results you are getting.
I suspect that most of your requests are failing in some way.

Hi,
We have had the server up to 1500 user threads while running beanshell
samplers that launch their own threads. This is on 2.6 kernel and the
important memory value for us was -Xss128k this limits the amount of VM
stack space reserved by each thread at the OS level. The heap will only
matter if the objects you are creating in your sampler need a lot of memory.
The other things to look out for are ulimit values. (Assuming you are
running it on Linux of course).

I find it hard to believe that Jmeter could successfully run 3000
threads on a single JVM instance with a gig of memory. Mine craps out
with just 10 threads.
