[jira] [Created] (HBASE-15971) Regression: Random Read/WorkloadC slower in 1.x than 0.98

             Summary: Regression: Random Read/WorkloadC slower in 1.x than 0.98
                 Key: HBASE-15971
                 URL: https://issues.apache.org/jira/browse/HBASE-15971

            Priority: Critical


branch-1 is slower than 0.98 doing YCSB random read/workloadC. It seems to be doing about 1/2 the throughput of 0.98.

In branch-1, we have low handler occupancy compared to 0.98. Hacking in reader thread occupancy metric, is about the same in both. In parent issue, hacking out the scheduler, I am able to get branch-1 to go 3x faster so will dig in here.
