Subject [jira] [Commented] (GIRAPH-329) Improve network performance
Date Fri, 21 Sep 2012 08:17:07 GMT

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.

> I have been working on some network improvements that appear to give 1.5x to 2x.  Unfortunately,
this is a very large change and very hard to split out.  Will give an update soon.
