Just to update this thread... Tcp protocol based openvpn had terrible jitter. while same hardware and almost identical configuration (using udp instead of tcp as the openvpn protocol) had no jitter at all So there seems to be something introducing a huge delay for small packets over tcp based

Hi Lads, I was testing out the openvpn port package and openbsd 6.0 and I found that while the tunnels are very stable, there is considerable jitter when sending small packets / small pings across the tunnel, while if I used large packets the latency was much more in line with network
