The PS/2 protocol is incredibly slow. Just sending two bytes over the wire via PS/2 takes 1.3 ms.

True. But that is throughout, not latency. Key presses are latency limited, not bandwidth limited.

But the latency of your keyboard will be increased by 1.3 ms just by putting it on a PS/2 port. That's more than USB polling at 1000Hz.
