frequently seriously affecting performance
[ https://issues.apache.org/jira/browse/YARN-8479?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16777559#comment-16777559 ]
Hu Ziqian commented on YARN-8479:
---------------------------------
Hi [~leftnoteasy]，[~daemon]
"As a result of our test that the scheduling speed of capacity scheduler is difficult to reach 5000/s in the production scenario." Where is the data 5000/s come from? Is there any test result or paper i can find?
Thanks

> As a result of our test that the scheduling speed of capacity scheduler is difficult to reach 5000/s in the production scenario.
> And it will soon reach the log bottleneck.
> My current work is to change many log levels from INFO to DEBUG level.
