[jira] [Comment Edited] (KAFKA-2528) Quota Performance Evaluation

    [ https://issues.apache.org/jira/browse/KAFKA-2528?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14739505#comment-14739505 ]

Yeah I think it is certainly doable, i.e. we can get very close to the target. I can run the experiment with and without BrokerTopicMetrics.bytesInRate using the same metric class as ClientQuotaManger.quotaSensor for calculating rate. This should tell us whether this difference is due to metric or quota implementation.

I did this report months ago. I recall that I tried get metric value from ClientQuotaManger and it should be lower than 1MB for that experiment. But I haven't written down my observation. Therefore I need to re-do the test.
