[jira] [Commented] (QPID-4089) Add latency tests into Java
Performance Tests
[ https://issues.apache.org/jira/browse/QPID-4089?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13404649#comment-13404649 ]
Alex Rudyy commented on QPID-4089:
----------------------------------
Hi Keith,
I am sorry I attached wrong patch with not fixed tests.
With latest patch attached at 30/Jun/12 23:08 I sorted majority of the issues.
Only issues left to resolve is a reporting order of "All Consumers" results. It appears as a first consumer result now instead of the last as it was before. At the moment I changed tests to pass but that needs to be changed.
Also, I have not fixed the issue with x-labels being displayed as ellipsis (...)
The rest of comments I tried to address in the patch attached.

> We need to implement a group of tests measuring latency metrics (minimum latency, maximum latency, average latency, standard deviation) by varying the following attributes:
> queue type
> message size
> number of producers and consumers
> selectors
> The publishing rate should be deliberately limited in such tests to never throttle the broker or exceed the consumption rate.
> Ideally, a special configuration parameter like expectedPublishingRate can be added to control publishing, however, we can use currently implemented "interval" parameter. We can also publish data in small batches with delays between batches.
> Also, it would be interesting to see comparison of latency vs throughput by varying the publishing rate.
> Publishing in AA mode is only required for initial latency tests.
