Hello everybody!
I configured the SSTP tunnel, where I use the RtrOS CHR v6.38.5 as a server, and the client RB2011UaS-2HnDB v6.36.3.
Both devices have external exchange time between which 70 ms.
BUT! When measuring time through VPN-tonel, I get a value 2-3 times more.
What can be associated with a drop in channel performance?

Tcp is the reason. Use l2tp instead because it uses udp.
