500kB/s on Ubuntu, 2.5mB/s on Windows. Both OpenVPN same settings.

Hi AirVPN team,

 

 

On the same machine I have windows and ubuntu.

 

On Windows:

* Windows 8 Pro

* Advanced Firewall used to limit internet traffic to only be through VPN

* uTorrent w/ port forwarding

* Usually peaks around 2.5mB/s. Max I've seen is 3mB/s+.

* Server: Sirius, TCP

 

On Ubuntu:

* 12.04 Server (with minimal desktop installed)

* UFW used to block all traffic out/in for internet except certain ports through VPN

* Transmission w/ port forwarding

* Usually peaks around 500kB/s. Max I've seen is 900mB/s.

* Server: Sirius, UDP

 

What can I do to increase the speed on Ubuntu? I think it's very odd that this is happening. Other variations are that the disks are different, but both are comparable 7200RPMs. 

 

Thanks

Is there as big a difference in speeds using the same port? It is strange that your Windows boot is so much faster. I have a machine which boots to either Windows or OS X. The OS X boot is about twice as fast in the tunnel.

I get better speeds using TCP 80 than the other ports but UDP 2018 which gives me the best performance.

@amnesty - it's interesting about OSX vs Windows.

 

I've setup the same port with UDP and now I'm easily hitting 2.5mB/s with the Ubuntu setup. The difference between TCP and UDP is significant it seems. I wasn't expecting it to be a multiple of 4 or 5.

I just hit over 6mB/s. That's faster than what Windows could achieve.

 

I'm pretty happy with the UDP results.
