( [id://3333]=superdoc: print w/replies, xml ) Need Help??
I've been trying to see if pre-allocating a array would make a script more efficient. So far my timing tests have not been conclusive. Should the following work?
my $preAllocDummy = 5000; # Fake call in order to pre-allocate the array. example(); # Real call. example(); sub example { # Trying a subtle pre-allocation hack. Supposedly the space # allocated for @array will be preserved for later calls. my @array; if ($preAllocDummy) { print "Trying to preallocate to max size $preAllocDummy\n"; $#array = $preAllocDummy - 1; $preAllocDummy = 0; return; } # Push stuff on the array here. }

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.
