I've noticed anywhere from 10-25% increases in real world disk I/O performance. There is no "file system performance limit" that magically caps sequential read/write speed to some arbitrary value. A lot of factors come together to give you a max speed. Obviously you are hitting a bottleneck somewhere that is lower than you think it should be. Does 3ware advertise the card is capable of 600 Megs/sec? It seems an 8x pci-e card would be capable of higher performance than that. - -- Thanks, Josh Paetzel PGP: 8A48 EF36 5E9F 4EDA 5ABC 11B4 26F9 01F1 27AF AECB -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.7 (MingW32) iD8DBQFJALr3JvkB8SevrssRAqleAJ9oJCRkv9jOVwxCqYDlfaSj+blweACdFsBP TUEcv2yhQ3CBk/tLC5JmyJs= =h/mH -----END PGP SIGNATURE----- From owner-freebsd-performance@FreeBSD.ORG Thu Oct 23 19:47:36 2008 Return-Path: Delivered-To: freebsd-performance@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 710E8106567B for ; Thu, 23 Oct 2008 19:47:36 +0000 (UTC) (envelope-from mike@sentex.net) Received: from smarthost1.sentex.ca (smarthost1.sentex.ca [64.7.153.18]) by mx1.freebsd.org (Postfix) with ESMTP id CA0248FC0A for ; Thu, 23 Oct 2008 19:47:35 +0000 (UTC) (envelope-from mike@sentex.net) Received: from lava.sentex.ca (pyroxene.sentex.ca [199.212.134.18]) by smarthost1.sentex.ca (8.14.3/8.14.3) with ESMTP id m9NIx3wM087525 for ; Thu, 23 Oct 2008 14:59:03 -0400 (EDT) (envelope-from mike@sentex.net) Received: from mdt-xp.sentex.net (simeon.sentex.ca [192.168.43.27]) by lava.sentex.ca (8.13.8/8.13.3) with ESMTP id m9NIx2NV059442 (version=TLSv1/SSLv3 cipher=DHE-RSA-AES256-SHA bits=256 verify=NO) for ; Thu, 23 Oct 2008 14:59:02 -0400 (EDT) (envelope-from mike@sentex.net) Message-Id: <200810231859.m9NIx2NV059442@lava.sentex.ca> X-Mailer: QUALCOMM Windows Eudora Version 7.1.0.9 Date: Thu, 23 Oct 2008 14:59:03 -0400 To: freebsd-performance@freebsd.org From: Mike Tancsa Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii"; format=flowed X-Scanned-By: MIMEDefang 2.64 on 64.7.153.18 Subject: improving Samba performance X-BeenThere: freebsd-performance@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Performance/tuning List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Thu, 23 Oct 2008 19:47:36 -0000 Are there any suggestions for a AMD64 RELENG_7 box to improve samba performance ?

I plan to switch to 7.0, though the system is running the ULE scheduler. The cpu's are amd64. I tested early on with bonnie++ and was getting similar numbers to the application test. It's a good idea to try it again so I will. The RAID is a RAID 6 as the application calls for data integrity though I do plan on doing a RAID 0 test as well. The array is something like 7TB total.
