Hello,
What is your machine configuration ?
If you mean the server, it is windows 2008 server R2, with 32 gb ram 2
processors. The data, app server and
webapps are all on this machine. Jmeter is running on linux. Not sure how
to check linux configuration.
What is your Xmx configuration ?
"-Xms2048m -Xmx4096m"
How does your test look like ? Can you show an overview ?
1. go to signon page http://host:port/welcomepage
2. sign off
I used jmeter proxy to create the text. So, at the browser, I waited
for the screen to fully open then clicked signoff.
There are lots of calls to content in between but I basically just want to
see how long it takes for many users to signon/off.
We initially decided to try splitting up the threads across two sessions
because we cannot understand why performance
with Grinder (our previous tool) was so much faster!
For how much time do you run it ?
I run for 100 threads, 1 run each.
Then two separate sessions of 50 threads, 1 run each.
Do you run the 2nd test just after the first one ?
WHen I split the test into two 5-thread processes, I run the second one
within one second of the first by quickly
switching to the other linux window and hitting enter key.
Did you try reversing the test , ie run 2x50 before 1x100 ?
Have not tried that.
What is your jmeter version ?
Jmeter version is 2.11
