People, processor of this hardware will be killed before the 100M ethernet
be the problem.

As far as i know, Raspberry PI ethernet over USB might be fine for DNS
too, but before it had issues with
large data transfers (ethernet driver hangs). No idea about now.

AIUI the problem with the RPi isn't so much that the Ethernet NIC sits on
a USB interface, it's that the RPi USB interface is very basic and requires
a great deal of host interaction to work. It presents a very high interrupt
load, and that can lead to problems.

Remember that the RPi, fantastic as it is, was developed as a low cost
educational aid. It can be used with great success in other fields, but you
should consider its limitations.

I'm using several to connect sensors, actuators, and such to a private
network, which it's great for - but I'd think at least twice before
deploying one as a public-serving host in user-experience-critical role in
a remote location.
