It's very unlikely to be a JMeter problem, so you need to do some more tests to try and establish what causes the difference when using 2 test hosts. What throughput do you get if you run the 50 thread test on the second host? Do you get similar throughput to a 50 thread run on the original host? What about running two 25 thread tests on the same host? Do you get similar thoughput to a single test? What sampler are you using to post the XML? > Thanks in advace, > Ravindra > --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
