At 16kb/s per connection , I think you have to ask yourself if you’re really helping. Have you checked your settings that you aren’t limiting your upload speeds?
Edit: people seem to be offended by this comment, so let me clarify by what I meant with “are you really helping”.
Torrent clients default to a fixed number of peers they download from. If you end up with only 16kb/s connections, you are being limited by those seeders in how fast you can download.
Whereas if there were less seeders but they could provide 1mb/s connections, you are limited by your own internet connection and are downloading full blast.
I hope that clarifies my statement.
We’ve been baking some cakes and cookies like that in the Netherlands for decades.
