Comment #11 on issue 2307 by asmeurer: Duplicate methods: as_coeff_mul and
as_coeff_Mul
http://code.google.com/p/sympy/issues/detail?id=2307
The answer is, it isn't comparable. I just reran it in master and got:
In [1]: a = 3*Mul(*[Symbol('x%d' % i) for i in range(100)])
In [2]: %timeit a.as_coeff_mul()
100000 loops, best of 3: 3.12 us per loop
In [3]: %timeit a.as_coeff_Mul()
100000 loops, best of 3: 8.96 us per loop
So it doesn't seem to have slowed things down any. And by the way, in
as_coeff_mul-remove with the args option set to True:
In [1]: a = 3*Mul(*[Symbol('x%d' % i) for i in range(100)])
In [2]: %timeit a.as_coeff_mul(args=True)
100000 loops, best of 3: 7.81 us per loop
So performance is not an issue here---the API is.
