stack updated HBASE-15971: -------------------------- Attachment: 098.png branch-1.png branch-1.hits.png 098.hits.png Here are graphs of me running ycsb -- both asynchbase and hbase10 -- on 8 servers pounding a single node carrying all regions. See how we do about 125k in branch-1 and 300k in 0.98. See how the handler occupancy is less in branch-1. > 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 > Attachments: 098.hits.png, 098.png, branch-1.hits.png, branch-1.png > > > 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)
