Maja Kabiljo commented on GIRAPH-388:
-------------------------------------

Eli, I'm not removing the information about partition id. I'm changing the way messages inside
one partition are stored.

> As per discussion on GIRAPH-357, in standard application chances that we get to use client-side
combiner are very low. I experimented with benefits which we can get from not having the client-side
combiner at all. It turns out that having a lot of maps in SendMessageCache, and then collection
inside each of them, really hurts the performance.
