Just to be clear that you're measuring apples to apples with OP:

You are measuring less than 40ms roundtrip latency on your Mac. Is this correct?

You seem surprised, but any sort of live production requires this. Check out SonoBus, it achieves adequately low end-to-end latency even with network delays in the mix.
