We strongly recommend that you always use strict in every script. Under strict, you must declare all your variables (my for lexical, our for global). Without strict, all variables default to 'package'. Your question becomes "Which type of variable is faster?" I doubt that it makes much difference.

In general, It is better to have a program that is easy to maintain than it is to have one that is marginally faster. ('strict' and 'my' offer several advantages to the maintainer.) The usual recommendation is to not even consider execution speed until you have a complete program that works correctly, but is unacceptably slow. At that point, profile it to identify the problem area. Write several versions of this code. Benchmark each with realistic data. (You will almost always be surprised by the result). Resist the temptation to make "easy changes" to speed-up other sections. Even a big improvement will make little difference in your complete program.

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 or How to display code and escape characters are good places to start.
