Two separate people today (one a colleague who works in geometric topology and group theory, the other a number theorist known to many on these lists) have said to me "Sage is still ridiculously slow on number field calculations" (quoting one of them).
I also know that when William wanted to do some large-scale computations over Q(sqrt(5)) he found it necessary to implement arithmetic in that specific field directly in order to get good performance; and a student of mine is finding similar slow performance for imaginary quadratic fields. I am only talking about basic field arithmetic here, nothing fancy. Does anyone know the real cause of this, or have any ideas on how to improve the situation? Surely the pari C library is not so slow? Is it the interface? I am CC-ing Bill Hart since I know that he is working on a new extension to FLINT which would do this.
