in reply to Re^2: The Deceiver
in thread Why does a Perl 5.6 regex run a lot slower on Perl 5.8?

I'm not entirely sure why the regexes were so much slower, unless they just never could actually match. In that circumstance, /.*FAIL/ would be a lot slower than /^.*FAIL/.

    And since perldeveloper removes the "whatever"s from the string the regexp will fail in the last iteration. So I would not be surprised if most of the wasted time was in the last iteration :-)
