The Nano will be fine as long as it uses an ATMega328 or similar.
DigitallOPerformance doesn’t work with the newer 32bit Arduinos or the latest non AVR chips. It works fine with all the 328 based ones though.
DigitallOPerformance converts the Arduino digitalWrite command in to direct pin addressing. This makes switching the pins a lot faster.
