Hi All, I am facing a problem where if i run a single jmeter instance it produces much better throughput than when i am running 2 jmeter instance.
Details about the test Script is very simple, it has just one sampler which post xml request to app server. Each thread posts one xml request and finishes. In one test, At the same time I simulated 50 Threads with no 0 rampup time. Lets say it produces x throughput. In another test I simulated 2 jmeter instance (not in master slave) from multiple machines with 25 thread (0 rampup) on each instance. The combined throughput I am getting in this model is much lower than in x. What could be the case of such a behaviour. Ideally the combined throughput should be equivalent to x. All the jmeter clients are server class machines with CentOS. Jmeter is running in non GUI mode. wht could be the cause of this behaviour? Thanks in advace, Ravindra
