HDFS-941 The trunk has moved on so the patch won't apply. There has been significant changes in HDFS lately, so it will require more than simple rebase/merge. If the original assignee is busy, I am willing to help.
HDFS-347 The analysis is pointing out that local socket communication is actually not the problem. The initial assumption of local socket being slow should be ignored and the design should be revisited. I agree that improving local pread performance is critical. Based on my experiments, HDFS-941 helps a lot and the communication channel became no longer the bottleneck.

The umbrella ticket is HDFS-1599, but the last comment from stack back in Feb highlighted interest in several tickets: 1) HDFS-918 (use single selector) a. Last comment Jan 2011 2) HDFS-941 (reuse of connection) a. Patch available as of April 2011 b. But ticket still unresolved. 3) HDFS-347 (local reads) a. Discussion seemed to end in March 2011 with a huge comment saying that there was no performance benefit. b. I'm working my way through this comment/report, but intuitively it seems like it would be a good idea since as the other comments in the ticket stated the RS reads locally just about every time.
