( [id://3333]=superdoc: print w/replies, xml ) Need Help??

The first thing would be to find where your program spends the most time, and look to see if that can be improved. You might look at the Devel::* modules, such as Devel::DProf, to help with this portion of the process.

You might also wish to consult several of the excellent books available. Some of the books I am aware of (and own) that might be helpful include Programming Perl, Advanced Perl Programming, Mastering Algorithms with Perl, and Perl Cookbook.

Title:
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.
