["Leif Hedstrom (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/TS-1405?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13443216#comment-13443216 ] 

Leif Hedstrom commented on TS-1405:
-----------------------------------

I'm wondering, with these improvements (they are improvements, right? :) ), could we get rid of inactivity cop, and enable the old code path which injected inactivity events ? I believe the inactivity cop was added as a response to "performance concerns" with the events, but right now inactivity cop can itself be a serious performance problem.

> when have more and more event in event system scheduler, it's worse. This is the reason why we use inactivecop to handler keepalive. the new scheduler is time-wheel. It's have better time complexity(O(1))
