Comment (by TobiasBg):

 Good question. I'm not really sure what the best strategy is to reliably
 test this for a real-world scenario. bobbingwhite seems to have done some
 simple testing in [http://core.trac.wordpress.org/ticket/17657#comment:18
 this comment], with the functions being 4 to 5 times faster.

 Given how many themes add several Shortcodes nowadays, just the many
 function evaluations in {{{get_shortcode_regex()}}} (especially {{{the
 array_map(...)}}}) might already have potential for savings. The PREG
 function is probably even more expensive than that, and saving that might
 also have potential.
 This is increased by the fact, that {{{get_shortcode_regex()}}} is called
 for every single post/page, so usually at least ten times on most blog
 pages - another factor of 10 for savings.
