Hello,
please explain, what is 'UDP acceleration' ?

If you use UDP acceleration you can get good result of throughput.
And UDP is using for NAT-traversal.

But this is not acceleration,
it is just speed loss prevention in conparison with
unvpnned user traffic.
IP-over-UDP = no speed loss, just small overhead about 28 bytes/pkt
(ip header + udp header of carrier udp packet + maybe some bytes for
crypting salt)
IP-over-TCP = ugly speed loss and overhead due to carrier session TCP ACKS for each internal data portion and speed limit over single TCP session

Very True! VPNs should use UDP by default and not TCP because of TCP-meltdown and the TCP overhead. Most VPNs are UDP based and that is why they are very fast.
Enabling UDP on SoftEther is more of a hack than the default behaviour. But it results in substantial speed gains compared to the default TCP mode.
