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.
