max 30-40 mbps per connection :-(

[ghulands 0]

Hi,

I am having trouble getting anything beyond 30-40 mbps over each vpn connection to AirVPN. I am connected to Sabik, Aquila, Merope, Chalawan and Alkes. I have attached traceroutes below. I am connect to Comcast Xfinity 1gbps/35mbps and have tested the speed to non-Comcast speedtest servers and hit around 850-950 mbps. I am using pfSense as my router/firewall with the 5 VPN connections as a gateway group. 

 

As you can see from the below traceroutes, there is no one common peering provider that could be throttling the connections. When I check the status page, all the servers I am connected to are below 50%.

 

Does anyone have any suggestions on how to improve performance?

 

Thanks in advance.

Hi,

 

Are you running OpenVPN on your desktop PC, laptop, tablet, router?

What is the CPU?

Hi,

 

Are you running OpenVPN on your desktop PC, laptop, tablet, router?

What is the CPU?

 

"I am using pfSense as my router/firewall with the 5 VPN connections as a gateway group."

 

The cpu is 

Intel(R) Atom(TM) CPU C3758 @ 2.20GHz
Current: 1700 MHz, Max: 2200 MHz
8 CPUs: 1 package(s) x 8 core(s)
AES-NI CPU Crypto: Yes (active)

Hardware crypto:	AES-CBC,AES-XTS,AES-GCM,AES-ICM

The box also has 32GB of ram and an SSD.

 

CPU usage when running a speed test or any other load never really puts the machine over 8%.

Hello!

 

Xfinity enforces traffic shaping, please check their policy. Normally OpenVPN with UDP is shaped most of the time for all broadband users, according to dozens of reports we have.

 

According to several customers of ours, the best throughput is obtained via tls-crypt connection in TCP to port 443 (in AirVPN, you get this connection mode to VPN servers entry-IP address 3 - OpenVPN 2.4 or higher version is required).

 

This connection mode has the ability to circumvent any specific shaping against OpenVPN and UDP, so you will remain subjected only to the general limitations and traffic shaping policies (and of course congestion, if any) enforced by Xfinity.

 

Kind regards
