Subject [jira] [Commented] (HBASE-7884) ByteBloomFilter's performance can be improved by avoiding multiplication when generating hash
Date Sat, 23 Feb 2013 03:10:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7884?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13584978#comment-13584978
] 

Jean-Marc Spaggiari commented on HBASE-7884:
--------------------------------------------

So 20% of 50% is still a 10% performance increase at the end. I will say it's significant
enought to consider it.
