why is it based on the raspberry when it has so terrible network interface? literally a +6 year board with a cual core and a gigabit interface can do this for better.
Also, newest revision of rpi (model 3 b+) is quad core 1.4ghz with gigabit lan. Overkill for a project like this.
Although, tests have shown it's not really gigabit in speed, but it is faster than the old 100mbit NICs previous Pis.
It doesn't matter if you dedicate it to this single use, you'll see more lag if it's also doing file serving stuff in the background for instance (also because of CPU use, not just networking)
