Avery Ching commented on GIRAPH-329:
------------------------------------
Please take a look! This is pretty important for improving performance. I
have run a few more tests showing this can significantly improve performance in
some cases (i.e. 2-10x) at very small numbers of workers and when we get close
to the memory limit by not overloading Netty.
