[...] As I told, I'm far from deep into those stuffs (I wonder why I'm listed here, ;-) if I can understand perhaps 5% of talk contents). So I got a simple try: I unlogged myself from beloved it.source so pulling away all my css and js tricks, and I "reload" the page, then I reload again. My browser, while reloading, is forced to get data from a dozen of differents URLS: it runs from it.source to en.source to bits.wikimedia.org then again and then again here and there.... needed time to reload a simple, very simple web page: 12 s. I guess, that if a plain html + css cached version (without any default js and perhaps with a single, included css section) of the page could be found, such a time would be much shorter.
