    Description

      When do performance test in HBASE-16625, i found it has the very big difference between Append and Increment (append is about 37% faster than increment).

      As stack mentioned in https://issues.apache.org/jira/browse/HBASE-16610?focusedCommentId=15493166&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-15493166, append and increment has been unified in server-side, and they looks the same in client-side.

      This issue is to figure out why the performance looks different between them.
