T Jake Luciani commented on CASSANDRA-8692:
-------------------------------------------
I also ran a test on cstar and see an improvement

nagle is this patch (sorry for the bad label)
nagle2 is 2.1 head with nagle on.
It shows this is an improvement over just enabling nagle.

> While researching CASSANDRA-8457 we found that it is effective and can be
> done without introducing additional latency at low concurrency/throughput.
> The patch from that was used and found to be useful in a real life scenario
> so I propose we implement this in 2.1 in addition to 3.0.
> The change set is a single file and is small enough to be reviewable.
