Packed version of WordPress

The wordpress admin panel is loading fast, but couldn’t it be better? What changes can be made to make it load faster?

Here are some simple suggestions:

1) WordPress could offer a packed version of all the core files, as well.

php_strip_whitespace or a find and replace function with regular expressions would do the trick, for example:

/\*[^*]*\*+([^/*][^*]*\*+)*/ = Remove PHP comments

2) Google page speed and Yslow says for example:
* Enable compression
* CSS-sprites
* Combine external CSS
