Sylvain Lebresne commented on CASSANDRA-6861:
---------------------------------------------
As said in CASSANDRA-6236, stuffs we can look at include (without being limited
to) what's in
http://normanmaurer.me/presentations/2014-facebook-eng-netty/slides.html (not
everything applies and not everything is garbage related (though most is), but
I think we can just make this ticket be "Implement any performance improvement
that Netty 4 can give us").
> Eliminate garbage in server-side native transport

> Now we've upgraded to Netty 4, we're generating a lot of garbage that could
> be avoided, so we should probably stop that. Should be reasonably easy to
> hook into Netty's pooled buffers, returning them to the pool once a given
> message is completed.
