Evaluating that integral to that degree of accuracy requires the integrand to be sampled 1023 times by the Romberg integrator in Free42. Depending on implementation details, other calculators may get there in one fewer iteration, which would mean 511 samples.

This is all independent of the speed of the hardware on which you're running the calculation; I'm only talking about how often the function has to be executed.

If you insert 1 STO+ 0 in your function somewhere, you can keep track of how often it is called, and at what rate. More than 1023 points to a buggy integrator; an invocation count that increases very slowly points to a slow calculator.
