Okay. From your post:
So, user code time: 0.521 + system code time: 0.260 = real time: 0.781. Makes sense! But then:
User code time: 0.633 + system code time: 1.522 = real time: 2.155s != 0.612s doesn't! The other examples seem to indicate -- although the "timing information" is equally futzed -- that if you force the real wc to run more slowly, then your fake wc runs less, more slowly? Is the lesson of your post that if you force wc to count characters -- which you can determine instantly from ls/dir -- and words -- which nobody is ever interested in; whilst also forcing it to use an 'unnatural' collating sequence that is equally of no interest, then your MCE::Grep can do what nobody wants done, less slowly than the system (which?) provided binary does, what nobody wants done? Great advert. With the rise and rise of 'Social' network sites: 'Computers are making people easier to use everyday'
Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
