    New Internet Land Speed Record! 6 Woody CDs in 78 seconds!
    Submitted by Netsnipe on Wednesday, May 22, 2002 – 15:57
    CD ImagesDespite the recent expression of disappointment over Woody’s delayed
    release by many, we can all at least be very proud now that Debian
    GNU/Linux is now officially the fastest operating system in the world
    setting a new
    record
    of 401 megabits/second over 12,272 km. Making the victory
    ever sweeter is that we’ve dethroned Microsoft who previously held the
    Internet Land Speed Record of 830 megabits/second over 5,626 km that
    was set in March 2000.
    Congratulations to the team consisting of the University of Alaska at
    Fairbanks; the Faculty of Science of the University of Amsterdam and
    SURFnet, the national computer network for higher education and
    research in the Netherlands, and thanks for very much for
    demonstrating to the world that Debian GNU/Linux still has what it
    takes to be up with the very best.

    Let’s keep our fingers crossed that one day we can also dethrone
    FreeBSD’s load handling record of two
    terabytes in a single day off a single server. The Debian project has
    an official press release here.

    Now if only someone could donate this connection (which is 8000 times
    faster than my poor overworked 56K modem) to me seeing how bad broadband in
    Australia is becoming.

    Ok,

    I admit it; I’ve been out of grad school for over 10 years, and my math is a bit rusty. So would someone PLEASE explain how/why moving Debian at 401 Mbps is better/faster/cooler than moving Microsoft at 830 Mbps? (aside from the obvious Jab about Microsoft being unsafe at any speed, of course.)

    Honestly, I don’t get it – why is this a new record? What am I missing?

    I thought doing *anything* with a OS other than Microsoft was better/cooler 🙂

    Have fun!

    Had to dig through a couple of levels of links, but I get it now. The land-speed-record is not just about bitrate, but about the product of bit-rate and distance. (in other words, the measurement is of “bit-meters”/second, not simply bits/second)

    When you think about it, this *does* make sense in terms of what they are trying to achieve; when you double the distance, you are doubling the transmission round-trip delay, which causes problems for TCP on LFNs (networking term: Long Fat Networks – usually pronounced “elephants”) So to win the award, they don’t have to just have fast hardware, but fast, well-tuned TCP stacks which can handle the special problems posed by LFNs. (There are a series of TCP options which deal with things like Window scaling, protecting against packet “serial numbers” wrapping around, etc. In order to win this competition, your TCP stack will need to support these extensions, *and* be well tuned (minimizing data copies, etc.)

    So it’s actually a pretty smart contest, designed so that to win the bragging rights, you have to deal with all the “real-world” problems involved in moving lots of bits over long distances the same way “real applications” would do it.

    Look at the distances involved.
