I get better performance with this:
my $parse_log_entry = qr/^$dateRegex/ms;
...
my $prevpos = 0;
while( $logfile =~ m/$parse_log_entry/g ) {
$count++; # count number of parsed strings
if ($prevpos) {
# print "Do something with $prevpos .. $-[0]\n";
# print substr($logfile, $prevpos, $-[0]-$prevpos), "\n";
}
$prevpos = $-[0];
}
You would use the substr expression above to access what you're currently capturing, though you don't indicate that what you're capturing is actually used at all. .

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).
