Hello, can someone explain to me why this script runs fast at first and then it becomes slower and slower. Basically I have this script and also myClass perl class created and what myClass does is do 3 simple get requests using LWP::UserAgent. It starts out fast, and then later it becomes slower and slower to the point where it's very slow, but if I start it again and modify some code to begin where i left off, it starts fast again. Is there anyway to have it work at the same speed? The workers don't take very long to do 3 simple get requests, so the workers aren't stalling at all. 
#!/usr/bin/perl

use threads;
use Thread::Queue;
use myClass;

use warnings;
use Fcntl ':flock';



my $q = Thread::Queue->new();

open(FILE,"database.txt");
open(FILE2,">>answers.txt");

$q->enqueue($_) while(<FILE>);

for(0 .. 9) {
        threads->new(\&worker, $q);
}

$_->join for threads->list;

sub worker {

        my $queue = shift;
        while( my $item = $queue->dequeue) {
                chomp($item);
                my $p = myClass->new();
                my $physics = $p->getRandom();
                flock(FILE2,LOCK_EX);
                print FILE2 "$item|$physics";
                print "$item|$physics";
                flock(FILE2,LOCK_UN);
        }
        return;
}
