*smacks forehead*
I got sloppy with the "my"s for sure. Ugh. Normally I'm fairly careful about such things - but I think I slipped up here for sure.
I went through and took out all of the "my" declarations and did put them outside of loops.

The result of that benchmarked at 268 seconds - *but* this is on my laptop that normally does it in 305 seconds (Athlon M 1G on WinXP with Active State Perl and half a gig of RAM). So a good speed up so far.

Then changing the calculation to be just before its for loop instead of up top.
That brought ended up one second slower than the above code.
So then moving it up above the highest loop made it go from 268 to to 286.
Then just putting in a number there and having no calculation at all in there brings it down to 264 seconds.
Doesn't seem like the improvement that I would expect to see after looking at your benchmark... but still an improvement - largely from that stupid "my" thing that I just screwed up on.

• 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).
