Content-Type: text/plain; charset=us-ascii Content-Transfer-Encoding: 7bit Sender: owner-freebsd-fs@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org Hi. Is there or has there been work on making the msdosfs (semi)asynchonous? I have a ZIP drive and it's /slow/. I checked why and saw it wrote all the clusters one by one to disk. Since devices like the ZIP drive don't (appear to) havea lot of cache, it slowed things down a lot.

I think DEVSTAT(3) is what you are looking for. you may also want to look at 'xosview' (in ports) or 'systat -iostat' (in the base system). -Alfred To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message From owner-freebsd-fs Thu Oct 14 22:57:51 1999 Delivered-To: freebsd-fs@freebsd.org Received: from panzer.kdm.org (panzer.kdm.org [216.160.178.169]) by hub.freebsd.org (Postfix) with ESMTP id 89BDB14D92 for ; Thu, 14 Oct 1999 22:56:48 -0700 (PDT) (envelope-from ken@panzer.kdm.org) Received: (from ken@localhost) by panzer.kdm.org (8.9.3/8.9.1) id XAA47532; Thu, 14 Oct 1999 23:56:25 -0600 (MDT) (envelope-from ken) Message-Id: <199910150556.XAA47532@panzer.kdm.org> Subject: Re: Measuring disk I/O bandwidth In-Reply-To: from Alfred Perlstein at "Oct 14, 1999 06:56:52 pm" To: bright@wintelcom.net (Alfred Perlstein) Date: Thu, 14 Oct 1999 23:56:25 -0600 (MDT) Cc: s198322@ccs.sogang.ac.kr (Young Jin Choi), freebsd-fs@FreeBSD.ORG From: "Kenneth D.

Yep. The devstat(9) man page also has information on the devstat system. > you may also want to look at 'xosview' (in ports) or > 'systat -iostat' (in the base system). If you want longer term results that are easier to parse, you'll probably want to look at iostat(8). systat -vmstat and vmstat(8) will also give you disk stats. (iostat gives the most options, though) Ken -- Kenneth Merry ken@kdm.org To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-fs" in the body of the message
