Being capped by AirVPN or ISP?

[skxBMrYsxlli 9]

I need some help in determining whether AirVPN or my ISP are capping my speed. I usually connect to the Manassas, USA servers, and I'm getting capped at about 15-20Mbps maximum downstream. With the VPN connection dropped, I can hit nearly the full 50Mbps that I'm supposed to be getting from my ISP. I've also tested a couple of other North American servers.

 

None of the usual problems apply: my firewall is a 3GHz Core 2 Duo with 16GiB of RAM and Ubuntu Server 13.04. I'm using UDP--I've tried 53, 443, and 2018. I'm using the latest OpenVPN build.

 

My configuration hasn't changed recently, but my speeds have.

 

Help from AirVPN staff would be appreciated.

 

Thanks!

Hello!

 

From our side, we confirm again that we don't cap anything. You can verify both from the servers monitor and other customers experience that there's no cap at 15-20 Mbit/s: the only "caps" are the maximum bandwidth that a server can provide (but you can see that Manassas servers have a lot of available bandwidth to give), the maximum throughput your ISP can provide to you from our VPN servers ISP, and the maximum bandwidth that is possible to reach, based on peering, routing, congestion and any other factor of best effort Internet, between your ISP ISPs, our ISP ISPs and anything in the middle. Whichever of them is lower, that's your "cap". Have you already tested connections to different ports (in particular, 53 UDP)?

 

Kind regards
