That's expected with latency and any protocol that requires a lot of back and forth.

This assumes we send and receive messages, one at a time.
It's better than I thought, but I suppose it doesn't scale well to
directories with hundreds of thousands of files, or a higher
latency link.

What about increasing the speed of light?
