That would be slower.

Much slower.

In fact I don't need to look at Benchmark to immediately say that your algorithm is O($b), which is slow indeed.

Multiplication is slower than addition in a chip because general multiplication is a complex operation. That said, multiplication is implemented efficiently. Repeated addition is much, much worse than the general routine except for a small number of exceptions. (eg 0, 1, 2.)
