I remember back in Kazaa/LimeWire/WinMX day, Azureus was a powerful beastly BT client. It is a massive beast that took my computer to fully load Azureus in 10 minutes. And that was the only powerful BT client at the time and people hate it because it is powerful but it is CPU intensive. BitComet, BitLord, FlashGet couldn't hold a candle against Azureus. Until qBittorrent, uTorrent and Transmission popped up few years after Azureus initial release. What a time to be alive back then.

Bigly is actually a vuze fork

The great thing with Azureus is if you could download bits of content somewhere else you could copy them in and it would take that into account.

This was quite handy for a big torrent of music videos back in the day with not enough seeders.
