Luke Lu commented on HBASE-5954:
--------------------------------
Thanks for the numbers, Lars! Are you using ext3? I wonder what the numbers
would look like if you enable barrier=1 in the mount options or just use ext4
(with barrier turned on by default). If the underlying fs doesn't do barrier,
the result is somewhat meaningless (you might as well use hflush).
