Dear Andrea, 
I am not a sir, but I will attempt to help as I see your question went unanswered on the users list 3 days ago.

Your question is not very specific, so it is difficult to answer. It sounds like you are currently using Matlab to try to optimize your function, but Matlab is slow. Perhaps you are using automatic differentiation in Matlab? I don't know much about their version of automatic differentiation, but I hear it is less thoroughly developed than ADMB. If you aren't using automatic differentiation, then switching to ADMB should be faster and more robust because it uses a better algorithm for optimization.

I do not know of anyone who uses Matlab to talk to ADMB, but lots of people use R to talk to ADMB (see R package R2admb). The open source nature of R made this possible, so similar projects might not be happening in Matlab.

Our purpose is to maximize a Performance Index (PI) relative to a function. This function has a rather complicated structure (within the main function other functions are called that call other functions...). Now we are optimizing the PI running a Design of Experiment (DOE), but this solution it's slow and requires large computing resources because we have to analyze all possible combination of DOE.
