I'm considering purchasing a new iMac and recently learned that Thunderbolt 3 can be used to create a Thunderbolt network bridge between two Macs. I assume that connection over Thunderbolt will be many times faster than an ethernet connection.
I also want both iMac's to be connected to my LAN via their ethernet adapters. Is it possible for both of these connections to run independently, simultaneously, so that each Mac can still "talk" to the internet and other devices on the LAN, but "talk" to each other at Thunderbolt speeds?
