Apparently my reply to your emails with these questions were insufficient to motivate you to study the subject, "These are matters of understanding you can best achieve by studying the subject, not by asking questions. The best way I can help you is by encouraging you to learn the material on your own. If you have trouble understanding some particular aspect, you will be able to formulate a question showing both your area of difficulty, and the fact that you made some effort on your own."

It depends but, in general, vacancy diffusion will be faster because the energy required to occupy a vacancy site is less that required for an interstitial site. Basically, an atom has to be small to fit into an interstitial site. Grain boundary diffusion is faster yet (typically) because that is where the disorder in the lattice is high so it is easier for atoms to move around.
