Hi

I'm trying to convert the below code to use LWP::Parallel. This shoul be faifly simple right? Well, I'm not sure where to start off. How do I limit the number of parallel processing to say 10 instead of just slurping the entire database, for example? 

use LWP::UserAgent;
 
    $ua = new LWP::UserAgent;
    $ua->agent("OpticDB LinkCheck/0.1");
 
    &connect_to_db;
 
    my $clock_start = time; # start timer
 
    $sth = $dbh->prepare("SELECT * FROM $DB_MYSQL_NAME");
    $sth->execute ();
 
    my $count = 0;
 
    while (my $ref = $sth->fetchrow_hashref ())
    {
 
        my $req = new HTTP::Request GET => $ref->{'url_en'};
        my $res = $ua->request($req);
 
            $res_id   = $ref->{id};
            $res_code = $res->code;
            $res_msg  = $res->message;
 
            unless ($res_code eq "200") {
             
                $count ++;
 
                $tmpl_show_record .=  qq|
 
                .. html to show erroneous records goes here ...
                |;
            }
    }
 
    $num_dead = $count;
 
    if ($count == 0) {
        &error_html("No dead links found!");
        exit;
    }
 
    $sth->finish();
 
    my $clock_finish = time - $clock_start; 
    $time_taken = sprintf ("%.2f", $clock_finish); 
 
    $dbh->disconnect;

Can anyone please help me modify the above code? Thanks!
