Subject [jira] [Commented] (GIRAPH-443) Properly size netty buffers when encoding requests
Date Wed, 05 Dec 2012 19:51:59 GMT


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, and create
the buffers as big as we need.
