Comment (by vdelecroix):
Hello,
Actually, a lot of time is lost for asking questions to the parent. For
quadratic number field, it is for asking about the attribute
_standard_embedding. I build a new patch with a bint attribute added to
NumberFieldElement_quadratic and the speed of comparison is divided by 10
(from 4 milliseconds to 400 nanoseconds). It will be updated as soon as
possible.
As modifying the structure of NumberFieldElement_quadratic is a major
change, I will split the patch into two parts : quadratic number fields
and general number fields.
Vincent
