Hi ken, Thanks for the thorough message. I am having difficulties with outputting my data to stdout, in the format that I wanted. The way I wrote it is when the individual threads complete, they execute this code:

 if( $response->is_success ) {

            print"\n\n", $counter_thread++,"th :", "Dumped Data Return
+ed:\n\n ", Dumper($response->decoded_content), "\n" ;

            print "Response code:  ", $response->code, "\n",
            "HTTP Response Message: ",
            $response->message, " ", "\n";

           } else {
             print STDERR $response->status_line, "\n";
          }

However, they come out in unsorted order. I am trying to print each thread in order with time elapsed for each thread, decoded_content in a neat way. As an example, the variable '$counter_thread' would print like 2,5,8, 10,7, etc. to stdout. Is this a threading issue? What is the best way to go about this? Chris
