> Off late netty 4 has earned so much praise in the community. For example, 
> https://blog.twitter.com/2013/netty-4-at-twitter-reduced-gc-overhead
> A switch to netty 4 enables a significant reduction in gc pressure and also huge performance gains. I started working on this last Sunday and have a patch that shows performance gains on the order of 15-25% (total execution time) for some applications at Facebook. However, I only tested it with hadoop_facebook. So there might be issues with SASL path. 
> I will release the patch today and want to open up a discussion if anyone is using the secure feature anymore. If not we can just deprecate it.
