Running a AVR Emulator (AVR8js) (benchmark ?!?!) #511

Open ricardojlrufino opened 4 years ago

ricardojlrufino commented 4 years ago

Hi doing some experiments running a emulator (AVR8js) in javascript interpreters, I found some substantial differences in performance, mainly in reporting the performance of the browser (chrome), running natively in nodejs the difference is even greater...

I'll share the results here, more information is here: https://github.com/wokwi/avr8js/issues/49#issuecomment-640276220
