Ahoj,
provozuju OpenVPN na Raspberry3, zatim jen jeden client. Vytizeni CPU pri 10Mbit temer nemeritelne. Takze bych se toho nebal. Specialni VPN akceleratory jsou potreba az kdyz tam mate velky provoz, hodne fragmentovane pakety pripadne mnoho pripojujcich se klientu. Preci jen RSA je narocny na pocitani a RPi zvladne jen 22 podpisu/s
Jinak cisla mluvi jasne :

Jinak, pokud se nepletu, toto je jednovlaknovy vykon. RaspberryPi 3 ma 4 jadra.
