I have performed a very simple test, using JMS Publisher sampler on JMeter, and a "jms.r11.Sender" test case on Harness , with similar test conditions: * No ramp-up, only one thread * same message size (1000 bytes) * same destination queue * same duration test period (60 minutes) * running as fast as possible (no delay between samples)
>From this tests, I observe that Harness generates almost 90% more messages than JMeter. As such we achieve greater throughput with one thread in a one minute test using Harness In order to get same throughput for jmeter, we must configure more threads. Tested with JMeter 2.6, and IBM Performance Harness for Java Message Service 1.2 ( https://www.ibm.com/developerworks/community/groups/service/html/communityview?communityUuid=1c020fe8-4efb-4d70-afb7-0f561120c2aa ) Any ideas of why JMeter generates much less load? I have even run jmeter with no gui, and saves results in CSV format. -- Bruno Antunes Software Engineer
