Please refer to the code you suggested and my OP.

I constantly read /var/log/messages for DHCPACK. When I find one, I parse the MAC and send the API request in a separate thread. The creation of the threads is not a problem. The issue is how can I bring back the result as quickly as possible back to the main process.

Example: I get 10 such DHCP requests in less than 1 second. My code luanches all the threads in less than a second. . But bringing back the threads into the main process is causing delays with the logic below/

The rough logic here: 
for(;;){
while ( <DHCP> ) { 

  # New ACK found. 
  # $macthreads{$mac} = new thread(\&launch, l_opts)


 }#while

  foreach $mac (keys(%macthreads)){
    if($macthreads{$mac}->is_joinable {
    $macthreads{$mac}->join;
    delete $macthreads{$mac};

  }

}#for

I used the Time::HiRes module. The first thread completes in 1 second. The last in more than 8 seconds.
