Dear members of the MediaWiki developer team,
having familiarized myself a bit with the MediaWiki architecture, I believe that I would punctually change the MediaWiki software in order to speed up the page load at the client side.
Namely, I believe that I can extremely significantly increase pageload speed by minimizing the rendering time inside the browser. More specifically, by reducing the number of block elements (and more generally, any (X)HTML elements), the expensive rendering of these will diminish. Using this method, I have obtained extremely significant speedups even on a quite reasonable machine (built by myself).
This optimization would require that I change the way that wikisyntax is translated into (X)HTML. Moreover, I'd have to redesign the "default components" of the pages.
Since MediaWiki is so extensively used, these optimizations may quite substantially reduce energy demands across the globe, and also lead to performance improvements among scientists and laymen alike.
