Heng Chen commented on HBASE-16652:
-----------------------------------

Thanks [~yangzhe1991].  As profile shows,  the main difference happens in 'get' operation
(about 5%),   let me dig it more.

> 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.
