Why BitTorrent Causes Latency and How To Fix It

Sivar recommends an article by George Ou examining why BitTorrent affects performance so much more than other types of file transfer and a recommendation on how to fix it. The suggestion is to modify P2P clients so that, at least on upload, they space their traffic evenly in time so that other applications have a chance to fit into the interstices. "[Any] VoIP [user] or online gamer who has a roommate or a family member who uses BitTorrent (or any P2P application) knows what a nightmare it is when BitTorrent is in use. The ping (round trip latency) goes through the roof and it stays there making VoIP packets drop out and game play impossible."

    You had 56K? NOT.

    No one ever had 56K, no one. If you got over 50, you were doing good.

    These days, the darkside^Wtelcos are degrading dialup on purpose.

    "Why BitTorrent causes network bandwidth to be used. And network packets to be sent & received. Really sometimes I wonder."

    Remember not everbody that is a nerd knows the specifics nor has the inclination to learn about the technology in sufficient depth. Most people are timestrapped or disinterested when it comes to domains outside their areas of job or area of their perosnal interests.

    Really, it's like complaining we have to teach brand new people the same things over and over again many people figured out many millenia ago.

    I think people forget that, not everyon is into tech, or is old enough yet to have become accustomed to it.

    So, let me get this straight:

    The geeks of slashdot acknowledge that P2P use strangles traffic on their LAN, and feel that some modification needs to happen to address this.

    However, when service providers complain about the negative effects of millions of people using P2P on their backbones, and take action to correct this, same said slashdot geeks get their panties in a bunch and cry fowl.

    I'm not taking one position over another. I'm just saying that I think this may be a big reveal about why a lot of norms have a strong mistrust and/or dislike of geeks. A lot of the time moral outrage is claimed when in fact it looks more like self interest.

    His articles look reasonable, but you can never tell with that guy.

    Well then twitter, why don't you analyze his articles and come to your own conclusion, instead of spraying ad hominems on him just because he doesn't hate Microsoft as much as you obviously do.
