If there is a lot of time at the beginning of the test, where seemingly nothing happens, I would take a few thread dumps on the JMeter side and look at those.

Hi, I am seeing a spike of threads on start-up, which I think is abnormal.For instance, I have set an Open Model Thread Group with following parameters:/ * Rampup-up time over 1 min */ rate(0) random_arrivals(1 min) rate(30/min) /* Test for 30 mins */ random_arrivals(30 min) rate(30/min)With these settings, we are seeing a spike of threads up to 160 on start-up before the system stabilises to a more reasonable rate afterwards (see attachment).This is causing false positives on our SUT. Can you please suggest any workarounds or fixes?
