Perl simple webserver not handling multiple requests simultaneously - multithreading

Question

I wrote a simple webserver which should continuously handle simultaneous requests. But, even after detaching the threads it doesn't handle simultaneous requests. Can someone help?
Webserver.pl
use HTTP::Daemon;
use threads;
my $webServer;
my $package_map = {"test" => "test"};
my $d = HTTP::Daemon->new(LocalAddr => $ARGV[0],
LocalPort => 80,
Listen => 20) || die;
print "Web Server started!\n";
print "Server Address: ", $d->sockhost(), "\n";
print "Server Port: ", $d->sockport(), "\n";
while (my $c = $d->accept) {
threads->create(\&process_req, $c)->detach();
}
sub process_req {
my $c = shift;
my $r = $c->get_request;
if ($r) {
if ($r->method eq "GET") {
my $path = $r->url->path();
my $service = $package_map->{$path};
if ($service) {
$response = $service->process_request($request);
}
}
}
$c->close;
undef($c);
}
test.pm
sub process_request
{
threads->create(\&testing)->detach();
my $response = HTTP::Response -> new (200);
$response -> header('Access-Control-Allow-Origin', '*');
$response -> content("Success");
return $response;
}
sub testing
{
my $command = 'echo "sleep 100" | ssh -o StrictHostKeyChecking=no -o ConnectTimeout=10 <dev_box>';
if (system($command) != 0) {
print "FAILED\n";
}
}

Here is code based on your example that works for me on Windows. Maybe you can show us how/where it fails for you:
#!perl
use strict;
use warnings;
use HTTP::Daemon;
use threads;
my $webServer;
#my $package_map = {"test" => "test"};
my $d = HTTP::Daemon->new(LocalAddr => $ARGV[0],
LocalPort => $ARGV[1] // 80,
Listen => 20) || die;
print "Web Server started!\n";
print "Server Address: ", $d->sockhost(), "\n";
print "Server Port: ", $d->sockport(), "\n";
while (my $c = $d->accept) {
warn "New connection";
threads->create(\&process_req, $c)->detach();
}
sub process_req {
my $c = shift;
while( my $r = $c->get_request ) {
if ($r) {
if ($r->method eq "GET") {
my $path = $r->url->path();
if (1) {
sleep 100;
$c->send_response( HTTP::Response->new(200, "OK", undef, "done\n") );
}
}
}
};
$c->close;
}
