Not really. PAL has a performant engine for label placement, but in various places it implements naive versions of some algorithms used in extraction of label candidates and that ruins the performance completely. The answer is to use more sophisticated algorithms. Of course one can try to optimize the speed of naive algorithms by running them on GPU, but that is not the real solution.
