Hi!

using Wireguard on the desktop/laptop/android I get my max internet speed, 250mbit.

When using Wireguard on both SBCs I get only 40mbit on the same Mullvad server.

It’s not a CPU limit, running speedtest with Wireguard only uses 7% on Orange Pi Zero 3 and 40% on the Banana PI.

Running speedtest on SBCs without Wireguard gives me max internet speeds.

To rule out possible Wireguard issue, I’ve set up a local Wireguard server and get max speeds from both SBC.

I’ve seen folks reporting similar issues with different SBC, Raspberry pi 2/3/4, but no solutions.

I contacted Mullvad support, but have yet to hear back from them on the issue.

Checked my MTU settings and they are fine.

Any ideas or suggestions?
