What surprised me was that parsing javascript took much longer than downloading is, even on a mobile phone connection! Anyone knows why after all these years we still don't have a way to download pre-compiled javascript?

Well, supposedly there's some bug in WebKit on the iPhone that causes some or all JavaScript to be parsed twice. That probably has something to do with it...

I wonder whether the output of Google's Closure Compiler is actually faster to parse if you discount the smaller lexical size.
