performance - How accurate are JMeter results -


i using jmeter test web application. able run test , can see results using various listener. reduce resource when run more 1000 thread run jmeter in non gui mode , after completion of test view result in graph mode. want know how accurate jmeter results(average/median response time). let suppose if 1000 users using web application , have response time of 20 ms. if simulate 1000 users using jmeter , see average ,median time in jmeter. since jmeter creating lot of threads , has own processing , possible average/media response time in jmeter higher actual.

as every load tool, need control injector :

  • regarding os config (tcp, system tuning ...)

  • machine power

  • injector runtime behaviour of cpu, swap ...

if injector in state, results accurate.
