Just to reiterate in case I wasn't clear, as long as the "computation in
Singular" just references a singular variable as output and "libsingular"
converts the output to Sage datastructures the latter is always going to be
slower. A good benchmark would be e.g. computing the dimension of some idea
where there is not much output.
Also, timing finally finished:
sage: timeit('test1(*P.gens())')
5 loops, best of 3: 2.2 s per loop
sage: timeit('test2(*P.gens())')
5 loops, best of 3: 1.49 s per loop
sage: timeit('test3(*P.gens())')
5 loops, best of 3: 32.3 s per loop
