How much does a VPN impact your torrenting speed?

Speed test running through my qBit container while on WIFI, if I use ethernet there’s practically no loss in my gigabit connection.

I have qBit set with ProtonVPN (port forwarding is enabled and working). Without a VPN I’m able to reach 10-12MiB, but with one I drop down to 3-5 which feels like too big of a hit.

Is there something I forgot to check, or could it just be my server of choice? I’m connecting to a relatively close server geographically.

I’m able to saturate a gigabit connection in both ways through my torrent client.

It’s gonna depend on your VPN provider, but I see about a 40% reduction in speed

1600/1600 out of my 2G gotta go server hunting every know and then

I am seeing a lot of talk about protonvpn. I’ve been using PIA for years and never tried anything else. Is proton faster than PIA? I have a 300mbps connection but only get 10mib down 2 up with qBitTorrent with the vpn on.

One thing worth noting as well is if you’re using WireGuard or OpenVPN connection type.
I noticed a DRASTIC improvment with PureVPN when I switched to a WireGuard connection.

I’m using PIA and I can fully saturate my 1GB download

There are VPNs that have dedicated torrent servers, you should look for those, I would say you would have fewer problems.

I experience the same difference in transfer rates as you… not as fast, I had to tweak thing to get to that 3-5MiB/s.
to watch something, I’m okay waiting 40mins securely versus 20 min unsecured. I usually watch it 2 or 3 weeks later anyways. and that max speed is usually reserved for new releases, older stuff is usually limited by availability.

I use proton and easily saturate 1gbit down

I always make sure to bind to the vpn network interface in qbit along with the listening port. Otherwise you wont find as many peers. I wrote a powershell script to automatically set the port in qbit when protonvpn connects, can find in my recent posts

I have proton, port forwarded with 500 mbps but I’ve never uploaded over 4 MiB/s. Not sure if it’s out competition by seed boxes or something wrong with my setup. My downloads can push 20-40 MiBs though.

It is a P2P enabled server, and I have the container automatically pick up the port just fine.

Tested some more, it appears to be more of a matter of ping or some other metric, because the speed loss is negligible when downloading.

Setting the interface is more important than binding in my experience, I have a split tunnel setup with a VPN inside a docker container and if I bind to the VPNs Ip then I cannot access the web interface, however if I set the interface that is sufficient to forward all of its outbound traffic
