When using qBitTorrent to download Linux ISOs, I am seeing that the total size of the download is one thing, then the total downloaded when complete exceeds (sometimes by almost double) that size.
For example:
Size Downloaded
900MB 1.56GB
1.6GB 1.91GB
Why is that thing?
More retransmissions than overhead. This is big concern when downloading movies and TV shows because there are attempts to poison the DLs for people (or there was when torrent was first created as a protocol).
