Subject: Re: [Qemu-devel] [patch] non-blocking disk IO
Date: Mon, 03 Oct 2005 20:33:30 +0200	[thread overview]
Message-ID: <4341797A.9080701@bellard.org> (raw)
In-Reply-To: <4340D479.7030301@stanfordalumni.org>

Thank you for the patch. I'll look at it ASAP. If there is no regression 
(in terms of bugs and performance) I will include it soon: I consider 
that non blocking I/O is now a critical feature in QEMU in order to get 
better performances.

Fabrice.
