Ariel Weisberg commented on CASSANDRA-8692:
-------------------------------------------

Commits are on github https://github.com/aweisberg/cassandra/compare/C-8692?expand=1

I left the buffer size for IncomingTcpConnection alone although it is configurable in a pinch. I increased OutboundTcpConnections buffer size to 64 kilobytes. I think the right default needs more research.

I want to make a unit test for the rest of OutboundTcpConnection. I am still figuring out the right way to do that.

> 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.
