If you have a Parallel Computing Toolbox™ license, you can try using that in conjunction with the ga UseParallel option. Other than that, I have no ideas for speeding up ga.

However, if you want a faster and more reliable optimizer, try using patternsearch. It solves the same problems as ga, and is easier to tune. The one thing that some people want is to find a global optimum. In that case, run patternsearch repeatedly, starting from a variety of initial points x0, such as

x0 = lb + rand(size(lb)).*(ub - lb);

Good luck,
