Subject [jira] [Commented] (HDFS-11814) Benchmark and tune for prefered default cell size
Date Mon, 07 Aug 2017 18:37:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16117009#comment-16117009

Andrew Wang commented on HDFS-11814:

Hi Wei, thanks for working on this. Did you test with a highly concurrent workload? One concern
is that performance will degrade with a lot of seeks. It would be good to look at disk statistics
to make sure disk throughput is fully saturated during the run.
