stack created HBASE-15971: ----------------------------- Summary: Regression: Random Read/WorkloadC slower in 1.x than 0.98 Key: HBASE-15971 URL: https://issues.apache.org/jira/browse/HBASE-15971 Project: HBase Issue Type: Sub-task Components: rpc Reporter: stack Assignee: stack 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
