I'm currently using OpenVPN, and it's too slow. Searching for alternatives, I've found https://www.softether.org/ which claims to be much faster than OpenVPN.
Can anyone approve this?
Are there any insights regarding SoftEther VPN stability (it is a new project, after all)?
The network setup is quite simple - 1 physical host (CentOS6), with 3 virtual guests (CentOS6, using KVM/libvirt). One of the guests is the OpenVPN server. Its 'tap0' device is bridges with (the virutalized) 'eth0' device.
Saying "too slow" is compared to accessing the same machine with SSH. When accessing the guest with SSH and X Forwarding (with reverse tunneling, without the OpenVPN), the graphics response is reasonable. When accessing it with OpenVPN, it gets toooo slow.
