Here's a sample little tight counter loop, running for 10 seconds on 3 different setups:
**MicroPython on Teensy 3.1: (96Mhz ARM)**
Damien gave me a hint, and told me to put the performance test inside a function, rather than global. It almost doubles the execution speed, which used to run 396,505 times.
Damien gave me a hint, and told me to put the performance test inside a function, rather than global. It almost doubles the execution speed, which used to run 396,505 times. With another hint, its up over a million now:
def performanceTest():
endTime = pyb.millis() + 10000
millis = pyb.millis
endTime = millis() + 10000
count = 0
while pyb.millis() < endTime:
while millis() < endTime:
count += 1
print("Count: ", count)
performanceTest()
**Count: 659,770**
**Count: 1,098,681**
