Eli Reisman commented on GIRAPH-309:
------------------------------------
Yes it would. I was not aware that the total messages sent was supposed to
reset each superstep. Either way I have run it using a number of algorithms
where I have a good idea what the counts should look like relative to input
data size, and its working great now.
Perhaps I will throw up a newbie JIRA to change the name of the counter to
reflect that it is a per-superstep count as everyone using Giraph here had
taken it to be a cumulative count on first glance as well. And including a
total msg counter might not be a bad thing either. Having the per-superstep
count has proven really useful, even when I wasn't sure if it was intended or
not! Thanks again for the fix.

> Currently, the message count is multiplied by the partitions, which is
> incorrect as it is a total message count for the entire worker. This affects
