note this is still without cake, and neither core seems to be saturated yet.

I do have a Turris Omni that I plan to move this to, but I was expecting this 
one to give me reasonable speeds on just a raw connection.

I will need a device with at least 3 ethernet ports (DSL, cablmodem, LAN)

Pete Heist has established that it can sustain 600Mbit through Cake without much CPU load or added latency.  Above that level the characteristics do degrade a bit.
