Hi, here is an untested piece of code( not written by me ) to show you how to use Parallel::ForkManager to run things concurrently. You could also use threads, but forking is simpler. You could also google for "Parallel ForkManager LWP" and get links like parallel web get with lwp::simple 
#!/usr/bin/perl
use Parallel::ForkManager;
use LWP::Simple;
use LWP::UserAgent ;
use HTTP::Status ;
use HTTP::Request ;

%urls = ('drudge'=> 'http://www.drudgereport.com',
'rush'     =>'http://www.rushlimbaugh.com/home/today.guest.html',
'yahoo' => 'http://www.yahoo.com',
'cds' => 'http://www.cdsllc.com/',);

foreach $myURL (sort(values(%urls))){
   $count++;
   print "Count is $count\n";
   $document =  DOCUMENT_RETRIEVER($myURL);
}

sub DOCUMENT_RETRIEVER{
 $myURL=$_[0];
 $mit = $myURL;
 print "Commencing DOCUMENT_RETRIEVER number $iteration
 for $mit\n";
 print "Iteration is $iteration and Count is $count\n";

for  ($iteration = $count; $iteration <= $count;$iteration++){
 $name = $iteration;
 print "NAME $name\n" ;
 my $pm=new Parallel::ForkManager(30);
 $pm->start and next;
 print "Starting Child Process $iteration for $mit\n" ;
 $ua = LWP::UserAgent->new;
 $ua->agent("$0/0.1 " . $ua->agent);
 $req = new HTTP::Request 'GET' => "$mit";
 $res = $ua->request($req, "$name.html");
 print "Process $iteration Complete\n" ;
 $pm->finish;
 $pm->wait_all_childs;
 print "Waiting on children\n";
}

undef $name;
}
