Oh, i had no doubt that it worked. I had trouble understanding *how* it worked. I write my perl in a very declarative and verbose manner, have never had reason to use map before, didn't know you could string commands together with commas to act on $_ without wrapping it in braces and didn't know why you were pushing undefs into the array.

In short: The syntax and lack of any explanation completely stumped me.

Either way, i have to admit that it is a superior solution to the wget method, as long as enough ram is available. Getting it to run enough threads to run at comparable speed to the wget method required 300 mb. However, due to the fact that it actually is possible to keep control of the ram use and that it runs entirely with Perl modules it is the better solution.

As such, thanks a lot. :)

FWIF, this is how i'm using it now: 
sub fetch_xml_data {
    my ($ids) = @_;

    my $dir = 'quicklook/';
    my $url = 'http://api.eve-central.com/api/quicklook?typeid=';
    my $thread_count = 20;
    my $Q = new Thread::Queue;
    my @threads;
    
    for my $id (@{ $ids }) {
        $Q->enqueue( $id );
    }
    
    for ( 1 .. $thread_count ) {
        push @threads, threads->create(
            sub {
                require LWP::Simple;
                while( my $id = $Q->dequeue ) {
                    say "Downloading XML file for id $id.<br>";
                    LWP::Simple::getstore( $url.$id, $dir.$id );
                }
            }
        );
        $Q->enqueue( undef );
    }
    
    $_->join for @threads;
}
