By default BitTorrent
supports a Maximun number of active torrents of 8 and a maximun number of active downloads of 5.
But if you indeed have a high bandwidth and there's a lot of people sharing the files you're looking for then you can adjust these number to your preferences.
These options available via this menu:
- Click on the Options menu > Preferences > Queueing
- In the Queue settings section (right pane) you can freely edit these values.
- Validate with the OK button
