I'm migrating because Transmission is horrible for a large amount of torrents (multiple of hundreds) due to the complete lack of concurrency capability. But I'll miss Transmission. This configuration has spanned many different operating systems and was migrated from transmission-gtk to transmission-daemon.
Translation of all the numbers:
Downloaded bytes: 64.4TB, 58.6 TiB
files added: 26.8 million.
seconds active: 3.84 years
session count: 802 times started
uploaded bytes: 909 TB, 827 TiB
It'll be easier to just fork QB at this point. Even features like "this torrent already exists in your list, would you like to merge trackers" are completely nonexistent in Transmission.
