i made requsted different profile from my ISP just for testing, i dont have comments for throughput.. but the ping test is fixed all the cases as the following: using 1Mb/s average ping ~ 43ms using 2Mb/s average ping ~ 43ms using 4Mb/s average ping ~ 43ms using 8Mb/s average ping ~ 43ms using 16Mb/s average ping ~ 43ms using 20Mb/s average ping ~ 43ms why the latency is equal... i was expecting less time..
