You have to open the phone and connect the device so it can cut power. The boot time is amortized across the 9 passcode attempts for each cycle.
The obvious fix is to write the attempt count first, before even bothering to check if the PIN is correct. The flash on iOS devices is a bit slow but not slow enough to matter in this case.

You don't even need a fancy machine to guess the most common pins if that's the case! Just let the battery run out and start again. Seems like a really poor setup if that's true.
