Question

1. Would you please tell me the max limit of no. of threads that i can use in JMeter 2.4 for conducting a load test?

2. Is there any difference in taking

Answer 1

There is no limit on Thread execution in Jmeter. Since its a java based tool, it uses java thread capabilities. In case of concurrent thread execution we need to taken care of machine configuration (ie. Memory size and CPU).

To avoid OutOfMemory issue try to run jmeter in NON-GUI mode with custom java runtime arguments in jmeter script inside apache-jmeter/bin/jmeter . Default is 512 MB.
