Subject: raid6: rmw writes all the time?
Date: Thu, 23 May 2013 14:55:47 +0200 [thread overview]
Message-ID: <knl3ke$n7t$1@ger.gmane.org> (raw)
Hi all,
we got a new test system here and I just also tested btrfs raid6 on
that. Write performance is slightly lower than hw-raid (LSI megasas) and
md-raid6, but it probably would be much better than any of these two, if
it wouldn't read all the during the writes. Is this a known issue? This
is with linux-3.9.2.
Thanks,
Bernd
