Set your global upload rate to approximately 80% of your maximum upload speed . If your upload is completely saturated, your computer cannot send "acknowledgment" packets to the seeders, causing them to slow down their transfer to you.

Set this to 0 (unlimited) unless you need to reserve bandwidth for other activities like gaming or streaming.

Adjust this to 100–200 . This focuses your bandwidth on active downloads rather than spreading it too thin.

Contrary to intuition, setting your upload speed to "unlimited" can actually slow down your downloads.

Your connection settings dictate how many peers you can talk to at once. If these are too low, you aren't finding enough sources; too high, and you can overwhelm your router.

Set this between 500 and 1,500 . This ensures you can connect to a vast pool of peers globally.

In the Connection tab, enable these options to let qBittorrent automatically ask your router to open a port.

For high-speed fiber connections, small adjustments in the "Advanced" menu can make a difference.
