[R] likelihood profiles for multiple parameters

I'm using mle2 for optimization of a multinomial likelihood. The model fit 
is not very good and I would like to look at the likelihood profiles. 
However I'm optimizing many parameters (~40) so using the function profile() 
takes forever and is not practical. How can I calculate approximate 
likelihood profiles? Is there a function for this in R?

thanks a lot for the help
