MOTU is claiming a latency of .92 ms
"Low, fixed network latency
Standard AVB network latency is fixed at 2 ms. MOTU AVB network latency is an astonishing 0.625 ms (fixed), even over 7 "hops" (switches) and hundreds of meters of cable. That's only 30 samples when the system is operating at 48 kHz. When adding the ultra-low processor latency of MOTU AVB interfaces, that's an astonishing 0.92 ms point to point, over seven switches and potentially hundreds of meters of network cables. By comparison, other proprietary networking systems have unpredictable, variable latency in the 2-5 ms range."
