I think I would make a distinction between theoretical and practical limits. A lot depends on how fast your objective function is, but I would say in general that if your objective function has more than a few tens of parameters you should probably be looking for some more specialized optimization code (e.g. AD Model Builder, finding a way to shoehorn it into existing routines such as nlme/lmer, etc.). I would be happy to be corrected though.
