How did you measure the bottleneck?
Over wifi, I can get around 600mbit to the router at best.
Running generic speedtest websites, I'm seeing myself top out at around 900mbit or so. Which should be enough for all my needs for long time.
Good old cat5e can actually do 2.5 gbps these days with newer network cards (Intel Z590 and Z690 mobos) and switches (kinda pricey though).
