I tried downloading
It gave a download speed of 1.15 MB/S or 9 Mbit/s with wget.
You have a 10 Gbit/s line and the overall bandwidth load at your site was about 1.5 Gbit/s.
How did you get this number?
So there should be enough excessive bandwidth to play with. Do you have a limit on the line speed per connection?
I then tried my own site:
This was with wget 29.8 MB/s or about 240 Mbit/s - my system has a 1 Gbit/s connection and the load was 100 Mbit/s.
I then tried to download via bittorrent from your site http://ftp.halifax.rwth-aachen.de/opensuse/distribution/11.3/iso/openSUSE-11...
It was something like 3.2 MB/s = 25 Mbit/s. Better than 9 Mbit/s
How do you know that you pulled only from halifax.rwth-aachen? When a site gets the iso it registers as a seeder with the tracker; it'll only be one more seeder among many. The torrent client will get a list of machines from the tracker and pull from many simultaneously, won't it? So if the bottleneck is not in your link you may be able to pull faster than from a single location. If the bottleneck is somewhere between you and the single source you may have lower flux even if both you and the source could be faster.
