Comment(by PolyBoRi):
Here some different timings with even better factor: opposite kind of
example: very tiny input, output and almost nothing to compute, replaces
some
singular interpreter call via pexpect with libsingular kernel function
call
{{{
#!python
from sage.libs.singular import function as sf
intersect=sf.SingularKernelFunction("intersect")
sage: P.<x,y,z>=QQ[]
sage: j=P.ideal(x,z)
sage: i=P.ideal(x,y)
sage: timeit("z=i.intersection(j)")
125 loops, best of 3: 5.12 ms per loop
sage: timeit("z=intersect(i,j)")
625 loops, best of 3: 60.9 µs per loop
}}}
