Softether Performance is worse than OpenVPN.

[Wes_Huang]

Hi all,

I follow the following blog to set up softether VPN.
http://blog.lincoln.hk/blog/2013/05/17/ ... al-bridge/

Target machine as a VPN client. ( SoC: AM3352 Memory:512MB)
Desktop as a VPN Server. (Intel I7, Memory:8GB )

I set up VPN with hardware encryption(aes-256) and I use iperf to test it's throughput . It's 64Mbits/sec.

On the other hand, I try to use OpenVPN with the following configuration.
https://wiki.debian.org/OpenVPN
https://community.openvpn.net/openvpn/w ... orks_Linux

I set up OpenVPN with hardware encryption(aes-256) too and use iperf to test it. The throughput is 85Mbits/sec !

It's weird, because I think softether's throughput should be better than OpenVPN.

I observed that cpu usage is 100% in these two cases.
I think that maybe I need to modify some softether configuration to improve it's encryption process.

Dose anyone have any suggestions?

I setup few softether servers with low end PC. all of them are working well. It can easily handles 5-6 concurrent users.

Something is wrong with your setup. I am getting around 700 MBits on an i5T. That is with SecureNAT.

I think because tun is used, OpenVPN got better result.
