You should be able to come very close to saturating a 100 Mbps Ethernet with that card, unless you have a card with the 21140-AA chip. Later chip versions are better (the AA version can't read multiple words in one PCI bus transaction). Using ttcp, that comes out to 100 * 1440/1538 = 93.6 Mbit/s application to application, or 100 * 1460/1538 = 94.9 Mbit/s if you turn off RFC 1323 and RFC 1644 support. I've measured 93.57 Mbit/s (with 1323/1644 support turned on) myself - between a PPro-200 (21140 card) and a P-133 (Pro 100/B card).

I believe its because the non-SMP motherboards don't have the hardware (specifically the IO APIC) nevessary for supporting the SMP code. Hence, if you don't have the hardware, NCPU=1 breaks. > 2.

I just checked this using a flooder and got a 8220 paq/s and somewhere between 95 and 98 Mbit/s. My problem seems to be that using ftp, rcp or nfs, i can go more than 58Mbit/s. I suspect the problem is the giant lock position since, for example, when using a reading process and a writing one (through pipe) i never have two running processes and perfs are half the one i expect. However, let's be happy with that. SMP is a pleasure and an impressive work. Thanks to the team !!. I wonder what will be the result when locking will be of fine granularity. Is the current silent in the SMP list the sign that SNAP-971225 is quiet stable ?

Far from it, there is a TON of stuff that needs doing. As some of you already know I run a one-man programming business, and I am currently on a project that soaks up every minute of the week. Because of this I will not be able to do any substantial SMP work for quite awhile. I will try to answer questions when I can, but don't get upset if the answers are slow in returning. We need some others to step up to the plate and take a few swings! Find something lacking in SMP and go for it. -- Steve Passe | powered by smp@csn.net | Symmetric MultiProcessor FreeBSD From owner-freebsd-smp Sat Jan 31 09:29:45 1998 Return-Path: Received: (from majordom@localhost) by hub.freebsd.org (8.8.8/8.8.8) id JAA08592 for freebsd-smp-outgoing; Sat, 31 Jan 1998 09:29:45 -0800 (PST) (envelope-from owner-freebsd-smp@FreeBSD.ORG) Received: from kaori.communique.net (kaori.communique.net [204.27.67.55]) by hub.freebsd.org (8.8.8/8.8.8) with ESMTP id JAA08587 for ; Sat, 31 Jan 1998 09:29:44 -0800 (PST) (envelope-from gjohnson@staff.communique.net) Received: by kaori.communique.net with Internet Mail Service (5.0.1458.49) id ; Sat, 31 Jan 1998 11:29:16 -0600 Message-ID: From: Tony Johnson To: "'freebsd-smp@freebsd.org'" Subject: SMP problems Date: Sat, 31 Jan 1998 11:29:15 -0600 X-Priority: 3 MIME-Version: 1.0 X-Mailer: Internet Mail Service (5.0.1458.49) Content-Type: text/plain Sender: owner-freebsd-smp@FreeBSD.ORG Precedence: bulk X-Loop: FreeBSD.org X-To-Unsubscribe: mail to majordomo@FreeBSD.org "unsubscribe freebsd-smp" I have experimented with my equipment and FreeBSD 3.0.971225.

Both of these boards use the 440LX chipset. P6DLF problems: 1) Can not disable keyboard checks, stupid AMI bios. 2) Sometimes refuses to boot after a BIOS config change. 3) Did not work with SDRAM. AMI's cheezy memory test ran but it would go no further. Same SDRAM works fine in two other MB's. 4) Stream reports only 90MB/Sec Copy, PII 233. 5) mptable reports all interrupts assigned to ISA bus. I hacked the correct PCI interrupts into an SMP kernel and got this beast to run but I won't be keeping it. The Giga-Byte 686DLX was plug-and-play.

(Gigabyte 586DX with dual 166MMX). They are recognized by the kernel: sio2 at 0x3e8-0x3ef irq 10 on isa sio2: type 16550A sio3 at 0x2e8-0x2ef irq 9 on isa sio3: type 16550A and they seem to work fine, but I get a few disturbing console messages: sio3: 64 events for device with no tp sio2: 124 more interrupt-level buffer overflows (total 124) sio2: 125 more interrupt-level buffer overflows (total 249) sio2: 125 more interrupt-level buffer overflows (total 374) sio2 runs at 460 KBaud. (Kernel thinks 115 KB) sio3 is unused / not-connected. I could't find anything in the man pages about the first error message, but the second one points to a "Problem in the bottom half of the driver". I'm not sure this is SMP related, but I seem to remember seeing something like this on this list last year. Or is the board just no good? Any idea what could be cause of this trouble?

I2O - did the I2O consortium ever release their specifications to the public? Is it now legal to write I20 software for which the source code is public? Last I heard this was going to be a big stumbling block to getting Linux or FreeBSD to run on it without making an "I2O" kernel module proprietary to a commercial company willing to spend $5K to join the consortium (and withstand being kicked out by Microsoft.)

A while back there was a Wired article regarding I2O. It described some anti-I2O sentiment by free software advocates, claiming it wasn't open. The article even had a link to a publicly available spec, but it was only there for a few days. I still have a copy stashed away at my ftp site if anyone is interested: ftp://ftp.pcnet.com/users/eischen/I2O/ver1-5.pdf.gz A quick search of the FreeBSD archives will give you the link to the [almost] original Wired article. It doesn't mention the I2O spec anymore. http://www.wired.com/news/news/technology/story/5343.html Dan Eischen deischen@iworks.InterWorks.org
