I am trying out a Login scenario where we have to simulate a
3 users/sec logging in to the application over a duration of 20 minutes.
So we thought of simulating it in this manner :Threads = 3600 RampUp = 1200 Duration = 1200 Jmeter starts firing the threads at 3 per second But fails to complete. i.e after spawning 230 threads it says OutofMemory error! And Exception in thread! -----Original Message----- From: sebb [mailto:[EMAIL PROTECTED] Sent: Tuesday, February 21, 2006 5:45 PM To: JMeter Users List Subject: Re: OutOfMemory Exception What do you mean? It fails - what is "it"? 3 users/sec - what does this mean? S. On 21/02/06, Chetana Anand <[EMAIL PROTECTED]> wrote: > > Ya it is..
