Why do you think TCP is faster than UDP when the reverse is actually true, see this (and many other reference on the internet): https://stackoverflow.com/questions/479 ... ster-is-it

I want to correct your misunderstanding.
In SoftEther VPN, NAT-T mode (in UDP) is wrapping whole HTTPS protocol.
Security strength is equal for TCP and UDP.

For performance, depending on the situation, either TCP or UDP may be advantageous.
UDP is advantageous in poor environments with many packet loss, large delay and narrow bandwidth.
TCP is advantageous in environments with few errors, low latency and wide bandwidth.
