stack commented on HBASE-15756:
-------------------------------

Pluggable for branch-1 could be a good way to go. I was suggesting not 
bothering w/ pluggable aspect because when options, users near always go with 
whatever is the default. If netty superior -- perf, options -- then lets just 
move there wholesale.

I've been messing with random read workloads trying to overrun a machine where 
all data is in cache so no i/o (working with [~danielpol]). I am having 
difficulty driving all CPUs. There seems to be always plenty of idle. After 
removing and temporarily hacking out the points at which we have contention, 
I'm still unable to use all CPU.

If you have a patch for netty, put it up and I'll give it a go.
