Thanks, i have done some examples of what i need for my goal (to compute puiseux expansions of polynomials whose coefficients may be algebraic numbers) and magma is still too slow. The problem is finding the roots of a polynomial with algebraic coefficients... and i need that a lot.
So i guess it is basically hopeless.
