I have gone down this path myself for doing 8k editing. TB3 attached SSDs IO to my Mac at about 3GB/s. The ones on my server connected over 10GB fiber Ethernet actually only reach about 800MB/s and I suspect that that macOS networking stack is just not at all optimized for 10G.

10GBit networking is really only 1.25GBytes per second, so 800MBytes/s isn't saturating the link, but is 64% of the way there. TB3 has a theoretical throughput of 40GByte/s so 3GByte/s => 24GBit/s is 60%. Realistically both are lower to the theretical link performance than I would have guessed, so there may be some bottlenecks involved beyond just computational overhead, but it makes sense TB3 was going to win assuming the storage had the bandwidth.

Yeah, was going to say, I'd take 800MB/s. I get a mere 180MB/s on this Drobo 5C (filled with 7200rpm HDDs) — theoretical max is 625MB/s.
