Does anyone have a bittorrent link for the Unity spins? I get 3-3.5Mbit
speed with torrent, and 200-400Kbit with that jigdo thing. Last month I
ran for five days and was still missing 27 parts, so it's kind of off my
list of usefully fast methods, using no parallelism at all, and not
letting users contribute to the supply.

The torrent speed that you obtained must of happened within the first
month of the distro's availability. My past experience with Fedora
Unity is that not long after release there were too few clients to
make a torrent useful. (Remember torrent clients only have to give
back 4 K-bits/sec of bandwidth ) You are better off using jigdo.
The torrent speed was early last week, maybe the 12th, using a live CD
boot on a Windows machine. Download of the original FC8 DVD iso image
ran up to 385KB/s according to the NIC speed applet, average was about
320KB/s over the total download. Pulling 9Alpha1 (a) took five days to
complete, (b) after day three I had to keep telling it to retry getting
all the things it didn't get, and (c) I didn't contribute anything to
the distribution, meaning that every client has to pull every byte from
the server.
I don't know where that 4K giveback comes from, maybe that's the lowest
you can set or something, I normally set max_upload_rate to 400 day and
800 night, so I don't impact outgoing bandwidth.
I can't see any way I'm better using jigdo, slower for me and more bytes
coming from the server... worst combination of features. See my earlier
post this morning on comparing the methods. Jigdo may be a good way to
create a new image when only a few bytes change, to get a full image it
just does a poor job for both the client and server.
