Subject [jira] [Created] (HBASE-16146) Counter is a perf killer
Date Wed, 29 Jun 2016 19:16:05 GMT

-----------------------------

             Summary: Counter is a perf killer
                 Key: HBASE-16146
                 URL: https://issues.apache.org/jira/browse/HBASE-16146
             Project: HBase
          Issue Type: Sub-task
            Reporter: stack


Doing workloadc, perf shows 10%+ of CPU being spent on counter#add. If I disable some of the
hot ones -- see patch -- I can get 10% more throughput (390k to 440k). Figure something better.
