The simple answer is use fewer observations or fewer iterations.
More specific advise is hard to give, as we haven't seen your
code. The are some general comments possible. You could try
adding starting values if you have good ones, as is often the
case in a simulation study. You could specify the
-derivative()- option, but that can mean a lot time spent on
programming and debugging, so if the time gain you receive from
the faster program will outweight the time lost programming is
an open quesiton.
