Hi, We are using JMeter 2.3.0 and java 1.5. We are not using any assertions or pre or post processors.
Also we are not using the SOAP request sampler. It did not matched with our performance testing requirement, so we have customized the Java request sampler to invoke web service request.

Java? And which samplers do you use? Do you use lots of Assertions, Pre or Post-Processors?
