Comment(by zimmerma):
> Except for special cases, "pow" uses log and exp, so the timing should
essentially be the sum for these two functions. Is it possible that you
hit a corner case with your experiments, or are the timings consistent
over several arguments?
then we should get about 210us for powint instead of 549us. Indeed, it
would be good to know the
exact arguments, so that we can try to reproduce with vanilla MPC (maybe
the problem is in the
interface between Sage and MPC).
For division, GMP 5 has a much faster division, which might benefit to MPC
too. But again, we
could investigate more with a vanilla MPC, if we know the exact inputs
used (with
exact_rational).
