After reading some more, I believe this is not the case. The VPNAzure page has this entry in its FAQ:

Frequently Asked Questions
Any method to improve the speed dramatically?
Yes. Install SoftEther VPN Client software on the home PC (client-side PC) instead of using MS-SSTP VPN built-in client.
A pair of SoftEther VPN Client and SoftEther VPN Server will try to make a fast UDP-based VPN link between them, even if both or any parties are behind the NAT or firewall. In order to make a fast UDP-based VPN link, SoftEther VPN exploits the UDP Hole Punching (NAT-Traversal) technique.
If your SSTP-VPN is very slow, install SoftEther VPN Client in the client-side PC. It will surprise you at high-throughput and low-latency.
Can anyone confirm?
