The channel-pool seems like a good idea and so does the bandwidth metrics, but how about a JIRA for each one?


http://svn.apache.org/repos/asf/giraph/trunk/pom.xml
<https://reviews.apache.org/r/6008/#comment21018>

    added this as a separate JIRA: https://issues.apache.org/jira/browse/GIRAPH-280



http://svn.apache.org/repos/asf/giraph/trunk/src/main/java/org/apache/giraph/comm/NettyClient.java
<https://reviews.apache.org/r/6008/#comment21019>

    The sendBufferSize and receiveBufferSize parameterizations should go in a new JIRA : added GIRAPH-281.

    For consistency with other pipeline components, use new ByteCounter() here.

Thanks for taking a look at this Eugene.  Do you have any more comments, or is this ready to go?

Hi Avery, 

Thanks a lot for rebasing on top of those 3 new JIRAs.

If you don't mind I feel like there are three JIRAs in here still :)

1. netty optimization #1 shortcircuit to local doRequest() calls
2. netty optimization #2 connection pools
3. bandwidth tracking

I would like to extract two of them and leave one behind as GIRAPH-262 (so it would be 1. (netty optimization #1))

The reason I'm being so picky about it is that I've modified a lot of the same code in my GIRAPH-211 patch. So I want to carefully merge your enhancements into there. 


I am happy to extract 2 and 3 out today as I did yesterday for GIRAPH-280-282, if you don't mind kindly rebasing your patch on them. 

-Eugene

While I understand why you are saying this, I felt these changes were pretty close in nature as a set of optimizations.  They also somewhat depend on each other, so I could split up into patches, but would have to rebase after each commit I think.

I need the reference here so that I can print the metrics periodically in the client.  See NettyClient.java:237.

I'll put this in GIRAPH-281.
