Subject Re: JMETER performance - Processes & threads

Thank you Deepak. 

Should I be concerned about memory on the jmeter client, or on the server?

Regarding the system handling that much load, where is the issue-- on the machine 
jmeter is running or on my application server?  
I am running the exact same test, just changing the number of threads:

   one jmeter session running 100 threads by 1 run.   100 seconds

   two jmeter sessions (different unix windows) running 50 threads by 1 run each.    30 seconds

 most likely memory - If
 your OS has enough spare memory and you start up 1
 JVM with for e.g. 1GB RAM heap , it will be
 slower than if you start 2 JVM
 with the same
 memory (so effectively 1*2 =2GB RAM).
 might get the same result by simply increasing your memory
 when you
 start up your JVM (the Xms and Xmx
 parameters). - Just a guess - only you
 access to your machine
 its also likely that your system isnt actually able to
 generate that
 much load if you are seeing
 the swing you are seeing - What is the response

 apples to apples i.e. look at the
 indvidual requests using something like
 firebug and network tab rather than page render
 times) then you have an
