I figured I'd just ask my question about super-seeding in this topic instead of starting a new one... I hope it's not inappropriate.

I've read a comment by an uploader here that super-seeding mode will cause their upload speed to slow down if there are only a few leechers (in the beginning) and they are not sharing effectively with the swarm.

My experience with, and understanding of, super-seeding mode is that it seeks to prevent the distribution of redundant data, and has no (intended) impact on upload rate. So I'm curious as to how this unintentional side effect might actually come about. How can the piece distribution within the swarm have an impact on the uploader's rate? Is there a potential slow-down due to extra time needed to determine what pieces to send, or what?

Thanks!
