Slow performance with SoftEther

[rizwan602]

Hello,

I am experiencing slow performance with SoftEther. I have done a LOT of testing and I just can't seem to make it go faster.

I have installed SoftEther on many different servers. I have VPS servers with Dreamhost, DME Hosting. I also have dedicated servers with Dreamhost and Secured Servers LLC.

All of these VPS'es and dedicated servers have 1 Gbps uplink. I an SSH into the server and do speed tests (via HTTP get) and I get on average 50 MegaBYTES (yes megabytes) per second transfer speed. I also get the same speeds uploading test files. So speed is not the issue here.

At work we have a 50 Mbps connection. I can connect to other VPN providers (such as StrongVPN and using PPTP or L2TP) and get close to 50 Mbps speed.

But when I connect to my SoftEther servers, I only get maybe 15 Mbps speed. On all of the VPS and dedicated servers where I have installed SoftEther.

When I start a download test file, I only get maybe 7 Mbps. To get to 15 I have to start multiple download files. With StrongVPN I get close to 50 Mbps with a single download file.

I am using L2TP with no IPSEC. I am also using SecureNAT.

Can anyone help me with what is wrong with speed? I really need to be able to connect near the full speed of our internet speeds at work. Is there a configuration issue, or a setting in the virtual hub I can change? I tried changing tcpmsssize flag but no difference.

Thank you for your help.

SecureNAT is not fast. I recommend using LocalBridge
