Bin Chen commented on TS-1405:
------------------------------

the origin event schedule policy will schedule the event(event->timeout_at - now < 5ms).now new patch(v12) will schedule these event too.

> 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))
