Is ULE scheduler stable in 5.2.1? We experienced a lot of errors when running apache benchmarks.

I believe ULE is stable in -CURRENT unless PREEMPTION is defined (which isn't by default). There were some changes to it lately which should fix the performance degradation in comparison to 4BSD in some cases. The author of ULE is interested in such reports as yours but only with recent ULE (read -CURRENT or RELENG_5). -- Michal Mertl From owner-freebsd-smp@FreeBSD.ORG Sat Aug 28 15:29:22 2004 Return-Path: Delivered-To: freebsd-smp@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id C89BA16A4CE for ; Sat, 28 Aug 2004 15:29:22 +0000 (GMT) Received: from smtp06.wanadoo.nl (smtp06.wanadoo.nl [194.134.35.146]) by mx1.FreeBSD.org (Postfix) with ESMTP id 70DA543D6B for ; Sat, 28 Aug 2004 15:29:22 +0000 (GMT) (envelope-from bsduser@wanadoo.nl) Received: from computer1.local (asn-c-1f3fd.adsl.wanadoo.nl [81.70.17.253]) by smtp6.wanadoo.nl (Postfix) with ESMTP id F386A175AD for ; Sat, 28 Aug 2004 17:29:19 +0200 (CEST) From: jan To: freebsd-smp@freebsd.org Date: Sat, 28 Aug 2004 17:31:41 +0200 User-Agent: KMail/1.5.4 MIME-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Content-Disposition: inline Message-Id: <200408281731.41860.bsduser@wanadoo.nl> Subject: no fun X-BeenThere: freebsd-smp@freebsd.org X-Mailman-Version: 2.1.1 Precedence: list List-Id: FreeBSD SMP implementation group List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Sat, 28 Aug 2004 15:29:22 -0000 Hi I installed freebsd 5.2 release yesterday and was ready to compile the kernel for the use of smp when i looked into GENERIC i saw that everything allready was ready for the use of both processors. i had not use freebsd anymore since 4.3 is it that when you install 5.2 it's recognizing the hardware as beeing a dual proc like the linux installers ? and adjust the kernel for it ? jan From owner-freebsd-smp@FreeBSD.ORG Sat Aug 28 16:41:50 2004 Return-Path: Delivered-To: freebsd-smp@freebsd.org Received: from mx1.FreeBSD.org (mx1.freebsd.org [216.136.204.125]) by hub.freebsd.org (Postfix) with ESMTP id 0966116A4E0 for ; Sat, 28 Aug 2004 16:41:50 +0000 (GMT) Received: from adsl-68-76-19-75.dsl.klmzmi.ameritech.net (adsl-68-76-19-75.dsl.klmzmi.ameritech.net [68.76.19.75]) by mx1.FreeBSD.org (Postfix) with ESMTP id 6A11543D49 for ; Sat, 28 Aug 2004 16:41:49 +0000 (GMT) (envelope-from luke@foolishgames.com) Received: from [192.168.2.49] (66.227.161.255.kzo.mi.chartermi.net [66.227.161.255]) (authenticated bits=0)ESMTP id i7SGisEh006706; Sat, 28 Aug 2004 12:44:55 -0400 (EDT) (envelope-from luke@foolishgames.com) X-Authentication-Warning: adsl-68-76-19-75.dsl.klmzmi.ameritech.net: Host 66.227.161.255.kzo.mi.chartermi.net [66.227.161.255] claimed to be [192.168.2.49] Message-Id: <24BFE8A0-F911-11D8-9677-000A95EFF4CA@foolishgames.com> X-Habeas-Swe-6: email in exchange for a license for this Habeas X-Habeas-Swe-3: like Habeas SWE (tm) Date: Sat, 28 Aug 2004 12:41:43 -0400 X-Habeas-Swe-8: Message (HCM) and not spam.
