Hi,as you do not give an example I can not be sure. But it sounds like 
the ever recurring problem of a function being evaluated with symbolic 
arguments. To ensure that the computations are done numerically, you may 
e.g. define:
f[x_?NumericQ]:=...

When I run the code it takes a hell lot of time. I do not know what mathematica is doing inside, actually I have another code in fortran that takes only a few minutes to do all the calculations but there are other problems like it dosent work for some parameter range.
