I'm about to put one of my Pi 3's to a good use for a VPN project. The internet in my country is censored like crazy. Many great websites such as pastebin and imgur are blocked. Not even gonna mention rampant state surveilance...
But whatever, I'd like to consult you guys about network speed.
Firstly, my download speed is 25Mbps (3125kb/s) and upload speed is 6Mbps (750kb/s). Here's the way I plan to make the whole thing: Incomming connection will be via ethernet interface, then Pi will login to my VPN service provider and broadcast the VPN enabled internet connection as a wi-fi SSID. I will be using this 5ghz ac adapter for it: https://goo.gl/fhZNkc I don't intend to use Pi's internal wi-fi module because I think it is a bit slow. Since both ethernet and USB ports share the same bandwidth, do you think Pi3 will get bottlenecked?
Another thing I'd like to ask is, whether this is gonna introduce some major lag or not (aside from my VPN service provider's performance). Because I play lots of multiplayer games on my PC and ping is very important for me. Mostly my ping is around 50 and I'd like to keep it there.
