Subject: [PATCH V3 03/18] multipath: change default path_selector to
Date: Sat, 12 Jan 2013 00:04:40 -0600	[thread overview]
Message-ID: <1357970695-3396-3-git-send-email-bmarzins@redhat.com> (raw)
In-Reply-To: <1357970695-3396-1-git-send-email-bmarzins@redhat.com>

My testing has showed service-time to be as good and occassionally
noticeably better than round-robin.  So the patch switches the
default selector to give better performance out of the box.
