First worl problem.

There is only 1 10Gbits port on router. I'm already using it (Usage never exceeds 3.5 Gbits).

I wanto to add second device, also in 10 GBits.

Hub or Switch ?

On the one hand, my fiber max out at 3.5 Gbits.

On the other hand, I might want full 10 Gbitrs for Pc to PC communication.

Do I need 10 ? 99% : NO. But there is this 1% when everything is so fast !
