Hi,
I've recently got a ZeroPi from FriendlyElec and I immediately installed Armbian Buster, so far is working great except for a minor issue with the Gigabit ethernet.
I'm planning to use it with Wireguard as server so I've made some performance checks first to test the actual network speed with iperf3.
What I discovered surprised me, the network throughput in upload from the ZeroPi is fine (900 to 950 Mbps) but the download seems to be limited to ~380 Mbps.

# $ iperf3 -c XX.XX.
