let say there are around 100 users/sec traffic available in prod and we were running a test in the same prod env with 1000 user/sec. when we monitor the JVM hazelcast thread counts for all hosts, we could see reduction in the count during our test window. how is this possible? Please find the screenshot attached. the dip in the thread count is the testing time, where more traffic went to the application.
