I find that TikZ compilations are rather slow. I often work with old computers and the LaTeX compilation is very fast but TikZ slows down the process. Externalizing the graphics helps but making a separate compilation for the graphics is not the idea in my opinion. I think that TikZ is still under development and it's a modern language so will his compilation become faster?
