I also ran a speedtest through the r2s to the internet during the above tests and there was no impact on bandwidth but latency increased from 11ms to 14ms.

I'm happy to say I see no practical impact to the USB3 ethernet.
As for the thermals and noise of this little router, I'm still watching.. it definitely got hot, I think hotter than when I just ran stress on the cpu
