Xeon may work in multi-CPU servers. Speaking of routers, you have multicore (2CPU x 4cores =3D 8cores) machine with 1-2-3 NIC's, and can't load other cores in CPU (earlier versions before FBSD 8.x). You need NIC with MSI (Interrupt Moderation) for better performance. 1. What kind of traffic did you expect? 2. What flow bit per seconds did you expect? I have PPPoE concentrator based on S3000AHV motherboard with EXPI9400 and EXPI9402 NIC's and Core2Quad Q6600 CPU and FreeBSD 7.2. This router may handle about 150k pps and 1Gbps for one direction of internet traffic. Do you need core i5/7 ? ------------941F11EA2ACF411C Content-Type: message/rfc822; name="1.eml" Content-Disposition: attachment; filename="1.eml" Delivered-To: gigabyte.tmn@gmail.com Received: by 10.140.158.8 with SMTP id g8cs326307rve; Tue, 16 Mar 2010 06:43:47 -0700 (PDT) Received: by 10.115.132.40 with SMTP id j40mr3105253wan.14.1268747027675; Tue, 16 Mar 2010 06:43:47 -0700 (PDT) Return-Path: <owner-freebsd-net@freebsd.org> Received: from mx2.freebsd.org (mx2.freebsd.org [69.147.83.53]) by mx.google.com with ESMTP id 14si3769994iwn.3.2010.03.16.06.43.47; Tue, 16 Mar 2010 06:43:47 -0700 (PDT) Received-SPF: pass (google.com: domain of owner-freebsd-net@freebsd.org designates 69.147.83.53 as permitted sender) client-ip=69.147.83.53; Authentication-Results: mx.google.com; spf=pass (google.com: domain of owner-freebsd-net@freebsd.org designates 69.147.83.53 as permitted sender) smtp.mail=owner-freebsd-net@freebsd.org; dkim=neutral (body hash did not verify) header.i=@gmail.com Received: from hub.freebsd.org (hub.freebsd.org [IPv6:2001:4f8:fff6::36]) by mx2.freebsd.org (Postfix) with ESMTP id D489F1565FF; Tue, 16 Mar 2010 13:43:37 +0000 (UTC) Received: from hub.freebsd.org (localhost [127.0.0.1]) by hub.freebsd.org (Postfix) with ESMTP id 49F1D10656ED; Tue, 16 Mar 2010 13:43:36 +0000 (UTC) (envelope-from owner-freebsd-net@freebsd.org) Delivered-To: freebsd-net@freebsd.org Received: from mx1.freebsd.org (mx1.freebsd.org [IPv6:2001:4f8:fff6::34]) by hub.freebsd.org (Postfix) with ESMTP id 314E2106564A for <freebsd-net@freebsd.org>; Tue, 16 Mar 2010 13:43:27 +0000 (UTC) (envelope-from antinix@gmail.com) Received: from ey-out-2122.google.com (ey-out-2122.google.com [74.125.78.27]) by mx1.freebsd.org (Postfix) with ESMTP id BAA5C8FC13 for <freebsd-net@freebsd.org>; Tue, 16 Mar 2010 13:43:26 +0000 (UTC) Received: by ey-out-2122.google.com with SMTP id 9so25793eyd.3 for <freebsd-net@freebsd.org>; Tue, 16 Mar 2010 06:43:25 -0700 (PDT) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; d=gmail.com; s=gamma; h=domainkey-signature:mime-version:sender:received:in-reply-to :references:from:date:x-google-sender-auth:message-id:subject:to :content-type; bh=FPPPWZUshZ59tess4sM0VeUPcC9ldMTrFE7t78E4Dcg=; b=n6hDqtNilTgLgr/O5s3lqJhhacFUDlOp2x7ZNZ5Ya4VSIhcjs0iIA45V0mzA5YtpOO cnasTtRhTF5oyKJMTGSl4kbbz5f1+fpKnw5f6AY/4b21/06iaDPRpZ7TfpgFRHjOlKKY NItRWLra2ir9qngbklRqSW3UWtljC8bK5KE1M= DomainKey-Signature: a=rsa-sha1; c=nofws; d=gmail.com; s=gamma; h=mime-version:sender:in-reply-to:references:from:date :x-google-sender-auth:message-id:subject:to:content-type; b=l98bXbfS9ok/xZoQj4Yv0zcD2xdFlovBoMQ7jh6hbFNDnzoyv0WQBAhGRvhNbuTgAz ricmvq2ObxztdbceDBuimbBx3Xu3ZOvsXodhoKzH8ul7yDJU7AP3frbI41+BOP6JpATo /YdMzpa8hVdMcvvUNJazIUGNslS8HfDa48Cec= MIME-Version: 1.0 Received: by 10.216.91.76 with SMTP id g54mr1159862wef.2.1268745321277; Tue, 16 Mar 2010 06:15:21 -0700 (PDT) In-Reply-To: <C7C53AE3.2441C%jon.otterholm@ide.resurscentrum.se> References: <C7C53AE3.2441C%jon.otterholm@ide.resurscentrum.se> From: Andrei Kolu <antik@bsd.ee> Date: Tue, 16 Mar 2010 15:15:01 +0200 X-Google-Sender-Auth: b752e4198f319cf8 Message-ID: <10263ac1003160615u2728634bv77a6704037e768a2@mail.gmail.com> To: freebsd-net@freebsd.org Content-Type: text/plain; charset=ISO-8859-1 Subject: Re: Choosing CPU for router X-BeenThere: freebsd-net@freebsd.org X-Mailman-Version: 2.1.5 Precedence: list List-Id: Networking and TCP/IP with FreeBSD <freebsd-net.freebsd.org> List-Unsubscribe: <http://lists.freebsd.org/mailman/listinfo/freebsd-net>, <mailto:freebsd-net-request@freebsd.org?subject=unsubscribe> List-Archive: <http://lists.freebsd.org/pipermail/freebsd-net>; List-Post: <mailto:freebsd-net@freebsd.org> List-Help: <mailto:freebsd-net-request@freebsd.org?subject=help> List-Subscribe: <http://lists.freebsd.org/mailman/listinfo/freebsd-net>, <mailto:freebsd-net-request@freebsd.org?subject=subscribe> Sender: owner-freebsd-net@freebsd.org Errors-To: owner-freebsd-net@freebsd.org 2010/3/16 Jon Otterholm <jon.otterholm@ide.resurscentrum.se>: > Hi. > > In the process to build a new router and want to choose the best possible > CPU for the job. > > Narrowed it down to the following: > > Intel Q9650 3,0Ghz > Intel i7-965/975 3,2Ghz/3,33Ghz > > What would be the benefit from a Xeon? > > Motherboard: Supermicro X8SBI-4LN. > RAM: 4GB > > The router will be running IPFW and Dummynet for traffic-shaping.

And of course there should be ECC memory. AFAIK you can't install more than one CORE cpu onto multicpu motherboard but you can do so with XEON.
