Modified my code in previous reply, now both server and clients reside in a single process. This makes the threading structure a little bit more complex. Don’t think this should replace the previous version of code, because of the architecture difference, so just create this new reply.

Also added yield() to all threads.

Code is tested.

use strict;
use IO::Socket;
use threads;
use threads::shared;

my $numClients = shift;
my $all_created : shared = 0;
$| = 1;

threads->create(\&server);
print "Creating $numClients clients...\n";
for (1..$numClients) {
    my $socket = IO::Socket::INET->new(Proto => "tcp", PeerAddr => "lo
+calhost", PeerPort => 7001) || print "Socket creation error: $!\n";
    threads->new(\&client, $socket, $_)->detach;
    print ".";
}
print "\nAll Created\n";
sleep 1;
$all_created = 1;
<STDIN>;

sub server {
    my $server = new IO::Socket::INET(Proto => "tcp", LocalPort => 700
+1, Listen => 5)
          || die "failed to establish socket\n";
    while (1) {
        my $client = $server->accept;
        threads->create(\&client_handle, $client);
        threads->yield;
    }
}

sub client_handle {
    my $client = shift;
    while (<$client>) {
        chomp;
        print $client $_ + 1, "\n";
        threads->yield;
    }
}

sub client {
    my ($socket,$id) = @_;

    sleep 1 while (!$all_created);
    
    print $socket "1\n";
    while (<$socket>) {
        chomp;
        print "$id <<== $_\n";
        print $socket $_ + 1, "\n";
        threads->yield;
        sleep 5;
    }
    return;
}
