What's New in the FreeBSD Network Stack

Posted by CowboyNeal on from the shiny-new-features dept.

jjgm writes "As FreeBSD 5-STABLE approaches, Andre Oppermann has produced a high-level presentation on the changes to the FreeBSD 5.3 network stack. There are many clever tricks for performance and scalability. Amongst other things, Andre claims that FreeBSD can now route 1Mpps on a 2.8GHz Xeon whilst Linux can't do much more than 100kpps."

    I know you're being funny -- but I think the answer most of us would have is "Hopefully not too long".

    If those changes made it into every OS that could use the improvement, then everything networked would find things just that much better without throwing away the old hardware.

    They don't need to. Linux uses *very* dumb routing algorithms at the moment. There is a fair amount of public research on much smarter mechanisms (one of which I guess FreeBSD would have used). AFAIK, this is getting implemented on Linux as we speak.

    your ignorance is great, pf is already ported to FreeBSD for quite some time as a kernel loadable module, and it will be integrated with 5.3-RELEASE. Have you copy-pasted a FreeBSD flaming text a year old ?

    Please.

    When even my laptop has 1Gbit networking built-in, I'm not sure how you can say "faster than 100Mbit exists, but it sure isn't common".

    And Mpps is a standard notation for packet forwarding....FYI.

    You GNU/LNUX zealots with your NIH syndrome. Nothing on earth beats OpenBSD for firewall usage, not even your piece of shit netfilter thing. When it comes to performance FreeBSD and DragonFlyBSD win hands down. But don't worry, you still get the hype.

    You've got it. Unlike what is perceived from Linux (all software must be free), BSD is about making all software better. That's the benefit of the BSD license that many people (usually GPL fans) don't understand.

      Sometimes I'm amazed by Linux developers humbling asking to use my software. "Go right ahead," I tell them, "That's why I put it under the BSD license!" But they still don't get it. While I appreciate the asking, it still find it strange that I get an email about once a quarter asking me to release my BSD licensed work under the GPL so it can be used in GPL projects.

      I guess it's hard for users of a "members only" license to grok the concept of "free for everyone".

    This is no different from the constant stream of improvements DFBSD folks appropriate from FreeBSD5, often with no attribution at all.

    Please point out an example where DFBSD doesn't attribute correctly. I think you won't find any. (and if you do, please mail the kernel-list, since the dfbsd crew is very strict about that)
