Not to mention this gives you a lot of flexibility and quite a battle tested backend, whereas the Go equivalents are still mostly in progress and less flexible.

Oh, and in the recent shootout, netty gets to 30,000 rpm, whereas Go peaks around 10,000.

First off, is was 14k vs 38k. Just wait until next benchmark update when they have switched to Go 1.1

Based on these results Go and Netty should be much closer: https://gist.github.com/errnoh/5320784
