Is this the trend? 

Looks like it - for this particular program, which primarily tests
bignum*smallnum multiplication.  We can't generalize from that
to (for example) division, which is difficult, and can be done in a
number of different ways.

gnu.math should be faster for logical (bitwise) operations,
because uses a 2's complement representation.
