And yes, of course, having a slow internet connection, no matter the download method, is one reason not to use a rolling release, or use factory assiduously. It takes me 13 hours to download a DVD at full speed and doing nothing else in the entire house. Realistically, it takes me about two days. So I usually don't use factory till RC time...
Let me jump in that.
If you want to download 4,3 GByte, you are going to download 4,3GB, no matter what tool you use...
Certainly. With torrent it is worse, in a sense, because you also upload, which can block or slow down other activities in the house.
If you have a limited down-link, and don't want to sqeeze out other traffic for some time, you have multiple options: - use rsync, and specify the download speed - use tc, and limited all traffic from a specific URL or port
wget and aria2c can limit speed, and they do it well.
Main advantage of torrent is, that the transferred blocks are small, so if a download get interrupted, you can continue without any loss of time I know other tools also have a "resume" option, but not all function properly.
aria2c resumes perfectly. It also does chunk checksum verification, so that an error is corrected by downloading that chunk again, not the entire DVD. Torrent does something similar. Rsync does it in another way. I even do things as brutal as hibernate a machine in the middle of a download, without warning... no big problem. Better if you stop it first, of course.
Other advantage of torrent is, that it reduces the load of the (initial) seeder. But if you do the download from a nearby university (instead of a normal hoster) speed or bandwidth are hardly of any concern to them.
As these are public mirrors that offer themselves, I'm sure it is not a concern to them. Surely they can limit the bandwidth they offer to us to what they can assume. In fact, aria2c will automatically switch to another mirror if the selected one is going slow, or even spread the load on several of them. torrent is a benefit when there is no mirror infrastructure or it is insufficient - as what may happen the day of the release of the final GM.
But i know the feeling, having downloaded an iso image over an 64Kbit link in the bad old days (and confronted with the telco-bill)..
Wow. Well, that was the main reason I paid for the SuSE professional box at the time... :-)) - -- Cheers / Saludos, Carlos E. R.
