Raghu Angadi commented on HADOOP-1841:
--------------------------------------

> This is very preliminary code but I would like to enhance the test to measure whether
this change is making any difference to performance.

Why do you think there will be any improvement in performance? This is really not performance
improvement in normal case.

> Hadoop's IPC Server currently writes responses from request handler threads using blocking
writes.  Performance and scalability might be improved if responses were written asynchronously.
