If you have an old aria2 knocking around like I did, it seems to be worth upgrading, via the 1 click install page. My old version wasn’t cooperating.
wget downloaded at full speed, but slowed to a trickle after a while.
The new version of aria2, is coping great except the -c (–continue) option couldn’t resume the download as it tried to create a directory the same name as the partial download file (which fails).
It’s really nice to get in hours, something that took many days before using a torrent.
There’s also some experience on the project mail archive recorded, the thread was originally suggesting pre-distributing torrent files, which drew out the information about the special arrangements.
If you can, after you have your downloads, please seed the torrents, to keep things smooth, now that the Akamai caches won’t be helping.
In my personal experience, it’s best to set a download limit just below the maximum, and restrict upload during download phase, when I’m in a hurry. Permitting seed later at full rate, without download goes much faster, presumably as a consequence of the way the ISP’s hardware works. So YMMV applies.
