It might not be faster because each call to the regex engine with matchText() or the other functions, will cause another parse and compile of the regex string by the pcre engine. Unless RR is doing some kind of pattern caching, which would be really neat, or worth a feature-request.
How true, testing this I get:
"perlRegEx = 13, PNLP = 3" using:
on mouseUp
put "Do a <perl>web search for Perl regular expressions</perl> tutorials," into myVar
put "<perl>(.*)(</perl>)" into regEx
-- perlRegEx
put the milliseconds into tStartTime
repeat with x = 1 to 500
put matchText(myVar, regEx, tElement) into bbYes
end repeat
put (the milliseconds - tStartTime) into ptTime
answer tElement
-- PNLP
put the milliseconds into tStartTime
repeat with i = 1 to 500
put offset("<perl>", myVar) into tNumA
put offset("</perl>", myVar) into tNumB
put char (tNumA + 6) to (tNumB - 1) of myVar into tElement
end repeat
put (the milliseconds - tStartTime) into otTime
answer tElement
-- show results
answer "perlRegEx = " & ptTime & ", PNLP = " & otTime
end mouseUp
