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.
}

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).
