Benedict commented on CASSANDRA-8341:
-------------------------------------
Ah, that's a good question: are we talking about queue latency or time spent
processing each queue? The two are very different, and it sounded like we were
discussing the latter, but the ticket description does sound more like the
former.

> context on how much time is spent percentage wise in each stage.
> Additionally can be used with littles law in future if ever want to try to
