Comment:
Before:
{{{
sage: K.<a> = NumberField(x^2 - 17*x - 8)
sage: K.pari_bnf();
sage: %timeit K.pari_bnf()
100 loops, best of 3: 3.01 ms per loop
}}}
After:
{{{
sage: K.<a> = NumberField(x^2 - 17*x - 8)
sage: K.pari_bnf();
sage: %timeit K.pari_bnf()
1000000 loops, best of 3: 1.56 μs per loop
}}}
