I created this in 2006:
http://wiki.typo3.org/TypoScript_technical_aspects

Its a BNF notation of TypoScript. At that time I also wanted to 
implement a TypoScript parser using flex/bison and yacc. But then PHP 
accelerators got more widely used and even proposed by the install tool 
and as TypoScript gets cached in a parsed and serialized form I dropped 
the idea.

Altough I think implementing many heavy-used methods of TYPO3 in a PHP 
module could speed things up quite a bit. I started to create an example 
project on github but it currently only implements "trimExplode":
https://github.com/kraftb/php5_typo3

Of course this only makes sense for methods which do not change on 
version-to-version basis as the effort for keeping the module uptodate 
would be too much. But I think "trimExplode" is a good example.

Right yesterday I coded my first mysql UDF (userdefined function) for a 
project. Maybe this would also be a possible entry point for optimizations:

But finally all heavy-load sites make use of some content caching 
mechanism which involves not to call PHP at all. So either 
"nc_staticfilecach", varnish or some CDN like akamai. So this 
optimizations would make sense to reduce energe requirements of servers 
for generating pages and increase page generation time a bit ...
