simplify(..., exp)

simplify can do a lot of things, and is generally quite expensive in terms of resources if you allow it to try all the different kinds of simplification available. It's more efficient to tell simplify to do a particular kind of simplification. In this case it sounds like you want to use simplify(..., exp). For example (I didn't try 400000 terms, but hopefully it scales):

> expr:= add(i/(i+1)/exp(i),i=1..40000):
ti:= time(): Q:= simplify(expr,exp): time()-ti;

Thank you

it sped up the calculation by 4 folds that should help. Thank you
