          Issue Type: Improvement
          Components: recipes
         Environment: GNU/ Debian 
java 1.6.0_21
zookeeper trunk (svn info shows Revision: 1141788)
            Reporter: ChiaHung Lin
            Priority: Trivial


The patch is provide according to wiki[1]. The source follows the description at tutorial[2].


However, from the mailing list it shows that this version is not optimized[3]. So is there
any chance anyone can point out which algorithm may provide better result for this construct?
I am happy to work on it, though it may take some time.
