PHP is for these tests, nginx and 256 to 512 PHP processes under PHP-FPM. Not a single process. If you put 40 Go processes behind nginx, each one allowed to use only 2 to 4 processors, you will get notably different results. Anyway, the tests show how hard it is to scale to many processors with a single process. It shows that the Java VM is really good at it (to be expected, Sun always had systems with insane numbers of cores).
