Eugene Koontz commented on GIRAPH-840:
--------------------------------------

Pavan thanks for the updating the review. It looks good and I recognize the significant work
it took; especially having to mess with the SASL channel handlers :) 

My only problem is that I cannot apply the latest patch:

https://gist.github.com/ekoontz/8950523

Am I doing something wrong? Do I have the wrong URL for the latest patch?

> 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.
