I am making a Load Script in which system has to fork 100 Processes, wait when 1st 10 processes are complete/Dropped/Terminated and start another 10 Child Process till the total child pumped reached 1000. I am using Parallel:ForkManager and there is a functionality which I dont know how to use. That is wait_children, wait_one_child. This is a snippet and not complete code. The last if has to wait till 10 child processes are finish and then start another 10 child process. I dont know how to wait for 10 child processed to finish. Here is the code I am writing 
    #Execute 10 number of calls
    foreach (1..$cps) {
        #Child Process Starts Here
        my $pid = $pm->start and next;

        if (defined $proxy) {
            $ENV{http_proxy}="$proxy";
        }

        `curl -o /dev/null -m 222 \"$Link\" 2>&1`;

        #child process ends here
        $pm->finish;
    }

    #wait for 10 calls to terminate and then pump another 10 calls.
    if ($callsRunning == $calls_at_a_time) {
        $pm->wait_children($cps);
        $callsRunning -= $cps;
    }
}
