    Hello Dear MQer,

    Have you never try this Performance testing tool ?

    # jmstestp
    Environment for creating a docker image running JMS performance tests for Persistent and Non Persistent messaging.
     
    This repository contains a set of files to help create a Docker image containing the JMSPerfHarness jar, IBM's Java 1.8 and a set of scripts to run an inital set of performance tests.





    From my run I got the following without any messages sent ????:
    Of course I verified  before the install,  running the basic sample to check with TLS and I succeed to send and receive msh but with the tool nothing ????
    my output:

    Did you read the manual @ https://github.com/ot4i/perf-harness/blob/8691287f3f1db72948bc6cd8da79ac7c05937a23/PerfHarness/doc/manual.pdf ?
    Did you install in Eclipse and debug?

    Hello,
    Yes I read the manual, My environment is Kubernetes container so I create an Image with OS, and MQ client and the Jar for JMSPerfHarness  and execute it inside the container, It didn't failed but doesn't sent any MQ message, I haven't see as well any error message ??
    Francois on your side did you experiment this Jar on K8S ?
    Thanks

    It isn't a tool I've used before, but the most obvious issue in that output is:

    ControlThread1: WorkerThread start interval (-wt=30) exceeded with no response from Sender1

    From what I understand of the tool, the main controller thread starts worker threads and waits for them to get through their initial setup before starting workload. The message is saying that the worker thread didn't respond that it was ready in the configured time limit.

    If this is running in a container, it may be limited on resources which isn't allowing the thread to progress quickly enough.

    I think you could get past the issue by setting a longer timeout with the -wt option.
