Z tego, co widzę, myślę, że nieskończone while pętla jest tutaj problemem.
PHP i gniazda
Jeśli nie możesz używać NodeJS, wypróbuj PHP z Sockets. Powinno działać całkiem nieźle!
Ulepszenia
Powiedziałeś, że szukasz ulepszeń. Oto one.
Dodatkowo użyłbym Angulara do powiązania danych pobranych z serwera z widokiem.

Trasy
Route::post('chat/refresh', function() {
$from = Input::get('from', null);
if (is_null($from)) {
$messages = Message::take(10);
} else {
$messages = Message::where('created_at', '>', $from);
}
return $messages->latest()->get();
});
Route::post('chat', function() {
return Message::create(['body' => Input::get('message')]);
});
Route::get('chat', function() {
return View::make('chat');
});
Model
class Message extends Eloquent
{
protected $fillable = ['body'];
}
Myślę, że kod jest dość prosty... Komentarze powinny wszystko wyjaśniać.
