Comment(by spancratz):
There's clearly something dodgy going on here. On my 32-bit laptop, with
a clean 4.3.1.rc0 install and only the patches from this thread,
{{{
sage: R.<x> = QQ[]
sage: S.<a> = R.quotient(3*x^3 + 3/2*x -1/3)
sage: 3 * a^3 + S.modulus()
-3/2*a + 1/3
sage: timeit('_ = 3 * a^3 + S.modulus()')
5 loops, best of 3: 14.3 s per loop
}}}
That is, it takes forever... Alex, could you perhaps elaborate on your
setup?
Thanks,
Sebastian
