[jira] [Commented] (HBASE-17877) Replace/improve HBase's byte[] comparator

    [ https://issues.apache.org/jira/browse/HBASE-17877?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15956065#comment-15956065 ] 

Lars Hofhansl commented on HBASE-17877:
---------------------------------------

[~vik.karma], can you attach your performance findings? (micro benchmarks and end-to-end)
In my own test I use to vet perf changes I found a 20-30% performance improvement - but I am using short key. The effect will be much less pronounced for longer keys (where memory pure bandwidth becomes the dominating factor)
