Actually, not to nitpick... ok, no, yeah I'm going to nitpick. Rewriting MediaWiki in any well accepted programming language besides PHP would have an extremely good chance of making it faster (well perhaps with the exception of our parser). I probably wouldn't pick Lua specifically as a target for rewriting, I'd probably Python or Node.js, bonus points if you use a flavor of Python that works async like gevent, Twisted, Tornado, etc...
We've spent a pile of development time on autoloading, message caching, etc... but no mater what we do there is ultimately a cost to re-doing the exact same setup of the environment over and over on every page view even if the step of compiling a PHP script is optimized. And frankly this may even hold true with HipHop. PHP is the ONLY programming language I am aware of that inescapably forces you to be stuck with this. Every other language has some server that will handle requests with a callback instead of globals and a full CGI style isolated script execution and will re-use the same pre-initialized environment over and over. And some will even do this async allowing the same pre-initialized environment to not only be re-used but used to simultaneously handle multiple requests from the same environment. ~Daniel Friesen (Dantman, Nadir-Seen-Fire) [http://danielfriesen.name/] _______________________________________________ Wikitech-l mailing list Wikitech-l@lists.wikimedia.org https://lists.wikimedia.org/mailman/listinfo/wikitech-l
