Subject: Re: [PATCH 7/9] xfs: push the AIL from memory reclaim and periodic sync
Date: Wed, 6 Apr 2011 14:33:56 -0400 [thread overview]
Message-ID: <20110406183356.GA23275@infradead.org> (raw)
In-Reply-To: <1302070758-17312-8-git-send-email-david@fromorbit.com>
The patch looks correct, but I wonder what the performance implications
of flushing the AIL every 30 seconds are. Did you benchmark the
patchset to see what it does to performance numbers for metadata
intensive workloads?
