Re: Anybody actually using gigabit ethernet?
I bought two of the cards in order to decide whether or not I wanted to use them in my research group's PII cluster. Right now, they're plugged into a 233MHz Pentium Pro and a 400Mhz K6-2 (using an Aladdin V-based board). I did a bunch of NFS testing over the gigabit link last week and didn't see any glitches. The only problems that I've seen are (1) the round-trip latency for small UDP packets is at least 50% higher than FastEthernet on the same hardware and (2) the round-trip latency is highly variable.

Anybody actually using gigabit ethernet?
I'm wondering if anybody out there has actually done any experimentation with gigabit ethernet boards using the Alteon Tigon driver. I know that it works on my hardware, but it's nice to actually have some feedback from people so that I know if it's actually working worth a damn. So far I have not heard a peep out of anybody, other than a couple of people who were nice enough to help out with some driver testing, and that was months ago. I usually consider this a good thing, because it means that at least nobody is complaining. But when people ask me hey Bill, how well do these boards work with FreeBSD? all I can tell them is that they seem to work okay in my limited test environment. This does not exactly provide a lot of motivation to go out and buy some gigabit ethernet cards. Also, I only have access to a limited selection of cards (I have a 3Com and a Netgear board, and others have tested AceNIC boards) so I don't know for sure if some of the ones that I claim to support actually work. (I don't have any reason to believe they won't, but Murphy's Law applies.) I also don't have access to a gigabit switch, so my testing is limited to blasting traffic between two hosts through a fiber patch. So, if anybody is actually using a Tigon-based gigabit board with STABLE or CURRENT, let me know. Is it working reliably? Is performance good? Is it bad? Inquiring minds want to know. -Bill -- = -Bill Paul(212) 854-6020 | System Manager, Master of Unix-Fu Work: wp...@ctr.columbia.edu | Center for Telecommunications Research Home: wp...@skynet.ctr.columbia.edu | Columbia University, New York City = It is not I who am crazy; it is I who am mad! - Ren Hoek, Space Madness = To Unsubscribe: send mail to majord...@freebsd.org with unsubscribe freebsd-current in the body of the message

Feedback on new drivers (was: Re: Anybody actually using gigabit ethernet?)
There should be a more general mechanism for this. I have the same problem with the USB stuff. 100+ people on the usb-bsd mailing list and only answers to directed questions. What about, like 'HEADS-UP', a 'FEEDBACK: drivername' message that should invite people to send 'it works' messages. And maybe provide a template of commands to cut and paste. Something like: (echo it works for me uname -a ident source code for driver dmesg | grep '^drivername' ) | mail -s drivername per...@address assuming that people are too lazy to type things in themselves.

You didn't read what I said. I don't have a gigabit ethernet switch. I only have cards.

This automatically implies 'using gb end-to-end.' As for corruption due to TCP sequence number wrapping, I don't know what to tell you. I never noticed such behavior in my tests, but that's why I'm asking for feedback from other people. The obvious answer to the TCP sequence number problem is RFC 1323. I assume anybody who wants to use gigabit Ethernet over significant distances *will* use RFC 1323, if they are interested in any performance at all. Otherwise the 64 kbyte window will kill you. As for me, I have tested the driver with Netgear cards. Works great here, I got 470 Mbps (effective application to application) with ttcp, running back to back on a PII-350 and a Celeron 300A (overclocked to 337, thus PCI bus clocked at 37.5 Mhz). The limit in my case is clearly the CPU. However I did *not* see any better performance when I turned on jumbo frames. Next I'll put one card in an old PPro-200 and see what I can get from that.
