Not 200Gbps of 16kB block writes, that's for sure.

Agree with you on the rest about kernel vs userspace, just taking issue with the bit about a single CPU core.

In context of time machine backups...

The link will be whatever the fastest network port you can get on an apple machine is. Its not 200Gbps - the apple end will be the limiting factor. A single core can probably fill that just fine.

And being pedantic - 200Gbps links are not a significant percentage of installed network ports in the computers in the world... so "almost any" is pretty accurate.
