Looks as if those forced line-breaks at 80 chars in the original post weren't such a good idea after all. Sorry.:(

The question about caching is a good one. I can't say for certain that caching didn't play a part in the performance boost (or in that case I guess I should say a perceived performance boost).

I later re-created the business end of the routine on another computer and timed both approaches. The results were similar. Haven't yet benchmarked it. I'm still, argh, a bit hazy on exactly how to use Benchmark. But never mind "hazy"--I will get make my way through the haze and try it. (To date the two approaches have been timed using only the 4nt command processor's own timer function--far from exact, to be sure.)

One noticeable difference between the regular expression I used and the one you used in your example here: I had only one set of parens in it. I don't know if this is likely to make a big difference in performance.

Thanks for the feedback, folks.

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
