      Description

      Profiling a simple speed of light topology, shows that a good chunk of time of the SpoutOutputCollector.emit() is spent in the clojure reduce() function.. which is part of the ACK-ing logic.

      Re-implementing this reduce() logic in java gives a big performance boost in both in the Spout.nextTuple() and Bolt.execute()
