Subject: Re: [PATCH 06/34] xfs: dynamic speculative EOF preallocation
Date: Tue, 21 Dec 2010 10:15:11 -0500 [thread overview]
Message-ID: <20101221151511.GA26127@infradead.org> (raw)
In-Reply-To: <1292916570-25015-7-git-send-email-david@fromorbit.com>
This patch causes tesr 014 to take ~ 870 seconds instead of 6, thus
beeing almost 150 times slower on mt 32-bit test VM, so I'll have to NAK
it for now.
