torrent speeds max 2MB/s

[avulicnik 0]

Hello, i have 100/12 connection (roughly 15MB/s down) and have no problem reaching those speeds without vpn.

However with vpn i dont get past the 2MB/s mark, its like something is throttling it. I have port forwarded, upnp/nat disabled, tried both utorrent and qbittorrent, same result.

 

Any ideas?

One thing it may be, if you are using Windows, there can be a problem as the latency increases, because by default Windows does not allow the "receive window" to increase. See:

For some background see:

Doing the tweaks in the first link above certainly helped me.

 

Also, if you are using Windows 7, you may want to downgrade the TAP adapter driver to an earlier version. See:

Downgrading the TAP driver also helped me.

I dont think thats the problem, its same for my synology which runs on linux, speed doesnt exceed 2 MB/s

I also noticed that when downloading via windows/firefox the speed which i download the file with is about half of what windows is telling me (rainmeter win8), does it have anything to do with encryption of the transfer? Maybe some extra bandwidth is needed for encryption/decryption? The speed is normal when downloading without vpn.

 

It doesnt really bother me im just curious.

This solution from the Staff solved the same problem for me awhile back give this solution a try.

 

 

Try to set the  sent/recieve buffer size to 256 kB (in "AirVPN" -> "Preferences" -> "Advanced" -> "General"). Click "Save" and start a new VPN connection.

 

 

Good Luck!

@S.O.A

That did it for me. Went from ~2MB/s to ~6MB/s Thanks.
