[jira] [Created] (HBASE-17324) PE Write workload results are wrong

Appy created HBASE-17324:
----------------------------

             Summary: PE Write workload results are wrong
                 Key: HBASE-17324
                 URL: https://issues.apache.org/jira/browse/HBASE-17324
             Project: HBase
          Issue Type: Bug
            Reporter: Appy


During writing, we are using BufferedMutator with size 2MB, so most writes return very quick because they get buffered. That's giving us avg. latency like 39us. Needs fixing.
