Comment (by zimmerma):
I confirm the speedup on my machine.
Vanilla 6.0:
{{{
sage: sage: E = EllipticCurve('37a')
sage: v = E.anlist(10000, python_ints=True)
sage: %timeit [ZZ(a) for a in v]
100 loops, best of 3: 15.3 ms per loop
}}}
With the patch applied:
{{{
sage: sage: E = EllipticCurve('37a')
sage: v = E.anlist(10000, python_ints=True)
sage: %timeit [ZZ(a) for a in v]
100 loops, best of 3: 13.2 ms per loop
}}}
