stack created HBASE-6270:
----------------------------

             Summary: If all data is locally cached, undo locking and context switching so
we are cpu bound
                 Key: HBASE-6270
                 URL: https://issues.apache.org/jira/browse/HBASE-6270
             Project: HBase
          Issue Type: Bug
          Components: performance
            Reporter: stack


See Dhruba's blog here towards the end where he talks about HBase: http://hadoopblog.blogspot.com.es/2012/05/hadoop-and-solid-state-drives.html

He says that when all data is local and cached, we bind ourselves up with locks and context
switching, so much so, that we are unable to use all CPU.
