Eli Reisman commented on GIRAPH-443:
------------------------------------

Wow, cool idea!

Do you find in the testing you arrive at an average size for a given job, 
configuration, and input data set for most of the buffers? would it be worth 
collecting an average, bumping it up a little, and reusing the same buffer of 
that average size until a larger one was needed, or is a direct buffer reused 
under the hood by Netty already?

> For some type of requests, it's easy to calculate the exact size of requests,
