Arduino Stepper Library Performance

Assuming that the stepper motor and the external circuitry is not a constraint, what is the max rpm the stepper library can support. 16Mhz Arduino Pro

Count the steps in loop() for a minute and report the number. Divide by the steps/rev for your motor rpm.

I suspect the stepper motor and the external circuitry will be the limiting factor.

Using a high step rate would be important if you are using a high level of micro-stepping, but then the RPM probably would not be high.

I understand that some Forum members have achieved high step rates with my Simple Stepper Code
