perl's regex engine is not fast,
making a backtracking regex (regex program/string) fast requires understanding backtracking and parsing at a level that you don't,
NFA-simulating-a-DFA and backtracing regex engines are both called regex engines but are 2 completely different things with different purposes and different semantics (longest match vs user specified ordered match)
