             Summary: lower query throughput on buffer pool dev branch versus master
                 Key: IMPALA-5762
                 URL: https://issues.apache.org/jira/browse/IMPALA-5762
             Project: IMPALA
          Issue Type: Bug
    Affects Versions: Product Backlog
            Reporter: Matthew Mulder
            Assignee: Matthew Mulder
             Fix For: Product Backlog


Running TPC-DS queries with concurrency of 80 on 1TB scale on a 7 node cluster I'm seeing average throughput of 596 queries per hour on the buffer pool branch versus 681 queries per hour on master. Need to investigate further to figure out why.
