My network is 100M though. Perhaps fs is responsible for your performance problem, your requests go through yet another user-level file system. If that's a problem for you, I may do some measures and tuning to help locate the problem, just let me know. --upas-ajxqaylylxfbxnukjuzghqpthe Content-Type: message/rfc822 Content-Disposition: inline Received: from mail.cse.psu.edu ([130.203.4.6]) by aquamar; Wed Feb 5 11:20:21 MET 2003 Received: from psuvax1.cse.psu.edu (psuvax1.cse.psu.edu [130.203.16.6]) by mail.cse.psu.edu (CSE Mail Server) with ESMTP id EB033199B3; Wed, 5 Feb 2003 05:20:07 -0500 (EST) Delivered-To: 9fans@cse.psu.edu Received: from mail2.snellwilcox.com (mail2.snellwilcox.com [195.173.15.4]) by mail.cse.psu.edu (CSE Mail Server) with SMTP id 95B301998C for <9fans@cse.psu.edu>; Wed, 5 Feb 2003 05:19:06 -0500 (EST) Received: from 127.0.0.1 by mail2.snellwilcox.com (InterScan E-Mail VirusWall NT); Wed, 05 Feb 2003 10:19:03 -0000 To: 9fans@cse.psu.edu From: steve.simon@snellwilcox.com Received: from ccMail by snellwilcox.com (ccMail Link to SMTP R8.51.00.11) id 3658374261; Wed, 05 Feb 2003 10:19:03 +0000 Importance: normal Priority: normal Subject: Re[2]: [9fans] diskless boot of one terminal off kfs machine Message-Id: <3658374261@snellwilcox.com> X-MIME-Engine: v0.90 MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Id: <3658374261-1@snellwilcox.com> Content-Transfer-Encoding: 7bit Sender: 9fans-admin@cse.psu.edu Errors-To: 9fans-admin@cse.psu.edu X-BeenThere: 9fans@cse.psu.edu X-Mailman-Version: 2.0.11 Precedence: bulk Reply-To: 9fans@cse.psu.edu X-Reply-To: steve.simon@snellwilcox.com List-Id: Fans of the OS Plan 9 from Bell Labs <9fans.cse.psu.edu> List-Archive: Date: Wed, 05 Feb 2003 10:18:33 +0000 Mmm, the disks are scsi (segate baracuda's on an Tekram (NCR) controller) What was strange was the slow speed of the mkfs | mkext. The machines are 400Mhz PII and a 350Mhz PII connected by 10Mbps ether so perhaps its just a sign of my ancient kit. Anyway it works, and I shall be trying it for real as when I get my venti server and DSL connection going. Anyone any opinions which scripts in in /bin/services I can safely copy to /bin/alt.services to run on /alt.net (the internet) - I want to be able to connect to my cpu & fs servers over the net but not get hacked (if possible :-) -Steve ____________________Reply Separator____________________ Subject: Re: [9fans] diskless boot of one terminal off kfs machine Author: 9fans@cse.psu.edu Date: 04/02/03 23:14 > If any of the fossil developers is interested I was using an fs interleaved > filesystem accross 3 fairly fast disks and got "disk: io=10021 at 8.779ms" > I got about 25 of these in 3 hours of mkfs | mkext before giving up. > The times increased slowly about 13ms but the counts stayed at 10010 +- 10. I think those are normal. Do you have DMA turned on? cat /dev/sdC0/ctl and make sure that the dmactl number is not zero. Russ --upas-ajxqaylylxfbxnukjuzghqpthe--
