No numbers are given for the C64, but the timing for the CBM4016 (with quite similar firmware/BASIC) should be similar. The Apple 2 input latency is even lower. Perhaps this is related to the fact that the Apple 2 firmware didn't use interrupts and polling might have been more efficient in this case.
