Olá, Não encontrei nada nem no manual e nem no google. O mas próximo que cheguei foi em um fórum onde um dos membros enviou o código abaixo e pediu para os outros testarem, mas não cheguei nem a ler o código. Da uma analizada e se funcionar mesmo me da um toque. Abs <?php /*** Bandwidth Tester 0.92 ***/ /* Please wait for 1.0 patiently! */ // How many bytes to test with.
