[jira] [Commented] (HBASE-12090) Bytes: more Unsafe, more Faster

["Vladimir Rodionov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-12090?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14147030#comment-14147030 ] 

Vladimir Rodionov commented on HBASE-12090:
-------------------------------------------

I have done some additional optimizations to *Bytes* class and now I can see >15% performance improvement in my Get(s) from block cache test (single thread).

Before: 44K gets per sec.
After:  52K gets per sec.

The similar improvement, I think, should be in a Scanner iterations from block cache.
