It's not, at least my posts aren't; it's a "why might Scott Robbins observe consistently poorer transfer rates with torrents than with FTP" thread.

I find that appeal rather unappetizing, actually. For example, SASA really sucks for modem users and more than mildly so for ADSL users. I dunno, maybe there are people with broadband who need to have SASA enforced on them, but nobody I hang out with has that problem. What _does_ need to be enforced is "no pig-piling on the server." And that's what bittorrent does well. Josh> Consider the TLUG tech meeting videos.

Hmm. I don't use bittorrent (I rarely download ISOs, although I admit I did do Gentoo a couple days ago, but that's a separate message). I wonder how many seeds are out there at this minute? I'm willing to bet that in fact there's only one seed right now, which is OSDL, and that very few of those who used torrents to get the videos even know how to be a seed, let alone actually did it. (At least the client I looked at defaulted to shutting down rather than seeding when the download was done, but that was back in the early days of bittorrent when bandwidth was much more expensive than it is now.) Josh> And the fact that the Bittorrent protocol seems to at least Josh> suggest socially responsible behaviour makes me happy. :) Well phrased. I know how to successfully leech (at least off the protocol described in Bram's paper, and in principle; I don't intend to actually try it, at least not on somebody else's torrent). Please note that SASA is not in general socially responsible behavior, unless everybody's alike and all goods are highly substitutable. It's easy to cook up examples where SASA, taken literally, is pretty close to the worst possible outcome. In the case of Bittorrent, with a group of peers with similar bandwidth and little bias toward particular individuals always being first or always last, SASA is an excellent heuristic. -- School of Systems and Information Engineering http://turnbull.sk.tsukuba.ac.jp University of Tsukuba Tennodai 1-1-1 Tsukuba 305-8573 JAPAN Ask not how you can "do" free software business; ask what your business can "do for" free software.
