If anyone is curious why Nightly is so fast: Mozilla prefers stability over anything else so a bunch of optimizations (like partial prerendering, or the efficient path for video on windows&mac) are pref'd off in release and enabled by default in Nightly. Even when a feature is done it will often bake in Nightly for up to 2 years for bug catching purposes. I personally think this is a bit extreme and is hurting the product.

maybe that's win/mac specific but on linux on my machine difference is negligible
