Comment(by bgoodri):
The original bench.sage was not very appropriate because sage was
simplifying the rational expression to 1 before passing it to Maxima or
GiNaC. So the difference in speed primarily reflected the difference
between interacting via pexpect and interacting via a library. The revised
bench.sage avoids this and there is about a 7x speedup. However, sage is
repeatedly calling gcd() automatically, and the performance would probably
jump if we could avoid that somehow.
