Not a performance issue per-se, but more an ugly unintended consequence of IPv6 issues: <i>peer-flooding</i> in torrent transfers. I use libtorrent to distribute my data sets and i&#x27;m seeing all the usual trackers are being flooded (DoS-like) via the vast available, in this case phony, IPv6 address space[1]. The unstated contention by agents of content owners being that bit-torrent can never do anything but wrong. Selfishly focused on their own content they&#x27;re statistically not utterly wrong, but they are using the design of IPv6 to poison the well for benevolent use.<p>[1] <a href="https:&#x2F;&#x2F;torrentfreak.com&#x2F;popular-torrents-being-sabotaged-by-ipv6-peer-flood-150619&#x2F;" rel="nofollow">https:&#x2F;&#x2F;torrentfreak.com&#x2F;popular-torrents-being-sabotaged-by...</a>
