poor data transfer speed

[Villain88]

Hello
I'm using version 0.25.0 and two servers with Ubuntu 22.04
After establishing a connection between the nodes, I observe a low data transfer speed
I have little experience interacting with libp2p and my tests showed that the speed slowdown does not exceed 15-20% of the channel speed when hosts are connected directly, without relays.
Where the problem could be?

EDGEVPNCONFIG=config.yaml ./edgevpn --address 10.1.0.12/24 --holepunch

Traffic capture using wireshark shows that network packets are sent directly

@Villain88 are you using the file-send and file-receive commands or you mean like doing scp between two nodes which are connected. I ask because the speed of the former is much better than that of the latter
