I'm attempting to make a link popularity checker in CGI (most will be tested and programmed for the command line until it's ready-- to remove unneeded hassle) and for something of this magnitude, speed is definitely a concern. www.marketleap.com has a similar thing to what I want to create and it takes like 10 seconds top to parse all the URLs and give you the report, it takes almost 10 seconds for 1 or 2 engines for my script. Can someone give me tips on how to severely increase the speed on this using modules that come with perl?

Code so far: 

#!/usr/bin/perl

use LWP::Simple;
use strict;

$|=1;

my $url = "http://sulfericacid.perlmonk.org";


my $altavista = "http://www.altavista.com/web/results?q=link:$url&kl=X
+X&search=Search";
my $google    = "http://www.google.com/search?hl=en&lr=&ie=ISO-8859-1&
+q=link%3A$url&btnG=Google+Search";





########################
# Altavista!
########################
my $altavista_content = get("$altavista");
my @altavista_lines = split /\n/, $altavista_content;

my $altavista_results;

foreach my $altavista_line (@altavista_lines)
{
$altavista_results = $1 if $altavista_line =~ m/AltaVista found (.*) r
+esults/; 
}


print "searched: $altavista\n";
print "results: $altavista_results\n";


########################
# Google!
########################
my $google_content = get("$google",  'User-Agent' => 'Mozilla/4.76 [en
+] (win-98; U)');

my @google_lines = split /\n/, $google_content;

my $google_results;
my $hits;

foreach my $google_line (@google_lines)
{
if ($google_line =~ /Results <b>\d+<\/b> - <b>\d+<\/b> of about <b>((\
+d{1,3}\,?)+)<\/b>/g)
{
$hits = $1;
}}
#Results <b>1</b> - <b>1</b> of <b>1</b>.

print "searched: $google\n";
print "results: $google_results $hits\n";
