Piracy: ꜱᴀɪʟ ᴛʜᴇ ʜɪɢʜ ꜱᴇᴀꜱ

I've been struggling to get ratios over even 1.0, most are stuck in the low 0.10 - 0.20 range. I don't seed off my gaming PC 24/7 because I don't want a VPN on all the time, plus I turn it off at night.

So mainly wondering if anyone has tips on a good setup to keep the PC seeding overnight, I'm running linux mint currently. I also have a RaspPi but I understand they are not great for torrents?

Is there any good way to compartmentalize a VPN? I.e., use the VPN for qBitTorrent only, and use my regular network adapter for other stuff (games, browsers, whatever).

I've tried a seedbox in the past and they're neat, but I'd rather avoid a subscription and just use my hardware. I'm using Private Internet Access VPN until my already paid for time is up in case that's significant.
