In network usage , my Tx/s and Rx/s values are doubled, i'm using a vpn and wifi tun0 and wlp3s0.

I think this is because gotop sums up the network activity across all the network interfaces. It looks like the usage stats of wlp3s0 + tun0 equals what's outputed by gotop. So we probably just need to hardcode some rules about ignoring vpn interfaces like tun0 from the network stats.
