Queue Manager Performance Analysis

Hi David,

For those examples you gave where your time command comes back with a high elapsed time, are those timings consistent when you run that same command multiple times, or do the timings fluctuate between acceptable and unacceptable for the same command when run multiple times?

Is this a non-global zone? If so, have you verified if the global zone is CPU constrained?

Thanks,
Tim

Subject: Queue Manager Performance Analysis

Hi listers,

We have a queue manager with which we are having issues with the response time for certain PCF requests, and I am hoping someone can help clue me in to things to look at.

note - while these time trials are using runmqsc, we are experiencing very similar completion times using a PCF client running off-host - runmqsc does not appear to be a part of the issue.

Appreciate any assistance anyone can offer at this time. The queue manager is running, but the delayed response times are impacting other functionality that relies on the queue manager (monitoring, remote configuration, etc.)

Thanks,
David
