Running time of bnfinit()

[Jeroen Demeyer <J.Demeyer@UGent.be>]

Hello,

do you happen to have a rule-of-thumb to estimate the running time of a 
bnfinit() call, say in terms of the degree and discriminant?

For Sage, we want to have a heuristic of when it's "easy" to compute 
bnfinit().


Thanks,
Jeroen.
