Subject [jira] [Commented] (GIRAPH-262) Netty optimizations and bandwidth tracking
Date Fri, 20 Jul 2012 16:15:35 GMT


Eli Reisman commented on GIRAPH-262:

Works well for me under a variety of loads, and dropping the netty server-side thread max
from 64 to 32 made it overload less on the cluster I test on, so that was a unexpected bonus
too! Great stuff!

> * Makes netty the default instead of HadoopRPC
> * Added optimization to handle requests locally when possible rather than go over the
> * Added TimedLogger to print only within a given time period
> * Added optimization for using multiple channels between clients/servers when bandwidth
is limited per connection
> * Added ByteCounter to track bandwidth across Netty (can be later integrated with GIRAPH-232).
> * Upgraded rat to 0.8 and excluded iml files (Intellij Idea)
