Doug Cutting commented on HADOOP-1841:
--------------------------------------
I think we need to both show that it doesn't slow things in the normal case,
and that it improves performance in this particular case (clients slow to
consume output). Do you have a realistic benchmark for that case?
> IPC server should write repsonses asynchronously
