you're mean. I generally limit at 70KB/s. That is fair enough.

That would be rather counterproductive when the upload capacity of his
Internet connection is only 32 kB/s (in theory; practically, it likely
tops out at 25 or so).

Download speed is used as an approximation for network proximity. And
yes, each machine downloads from multiple peers, but it tries to select
the fastest such peers.

Fair enough...

I don't think it matters does it? My ADSL maximum upload speed is about 45
KB/sec too, but if I let BT use all that then other web browsing etc grinds
to a halt. So I have the global upload rate limited to 32 KB/sec in my BT
client, and downloads still go at 600+ KB/sec if it's a popular file.

So you shouldn't feel bad about just stopping it then.

I suppose a more pressing point is that I shouldn't feel bad about a
bunch of anonymous IP addresses that I've never even met before. o_O
Damn, I'm pathetic and submissive even online...

My BT client had crashed, but it has 25kBps limit to upload and 100kBps

of 11654,4MB of upload. I'm honestly surprised that he runner-up is
openSUSE-11.1-DVD-ppc-iso (3934,7MB/9983,7MB). The top ratio goes to
openSUSE-11.1-GNOME-LiveCD-x86_64-iso (681,8MB/5597,3MB, ratio being 8,21).
Just leave it running and let the automation do the tricks :).

Not really; I have a 3 Mbps/384 Kbps ADSL line, and while it can take a
week or longer (especially since I throttle my upload speed to 20 KB/s
using SpeedScheduler because otherwise other things I need the line for
slow to a crawl), the method I use seems to work pretty well for me. I
guess it depends on the trackers you're using as well, though, and if
you're pulling recently posted files (I do) or files that are much older
where the number of peers is low to begin with.

Only if you have a fast enough connection. I measured my connection
(which sounds comparable to Andy's) and figured 80% of that IIRC. So on
the assumption that 20 KB/s is 80% of my measured (not rated) bandwidth
(which ISTR it is), then you're proposing that I'm being "mean" by not
using nearly 300% of my available bandwidth. Are you nuts? ;-)

The point is, though, "fastest such peers" depends on the utilization of
the peers. A peer that has a 3 Mbps upstream connection can perform
worse for you than a peer with a 256 Kbps upstream connection if there
are 50 peers connected to the "faster" peer.
