Thank @paolino . My router is supplied by ISP. I have check it and it is 100mbps. It's max download and uplaoding should be 12.5MB, the same as you said. I manage 12MB/s and it already reachs its max capability, I am happy. Before I play the setting, it was about 70% of its capacity. The windows reserve 30% of the capacity by some reason. @gabijgg's testing shows only 5MB/s, it may related to windows setting?@mysat-bs : You raeched with 12 MB/s maximum transfer speed of 100 Mbps LAN.
