Many of these algorithms are for arbitrary string searching; it's difficult to outperform Perl's regex engine. (Please note that the portion of my post which you did not quite implied that you can't pull in PCRE.) I suspect, but can't immediately prove, that code heavy with malloc/free temporary data may reach a point where it's faster in Perl than in C, but that depends on overcoming the overhead of op dispatch in Perl.
