a lot of people seems to be confused by what exactly wtfast and other programs such as actually do, let me make this clear to you, wtfast only increases ur TCP Package frequencies and ensures a more stable connection but in no does it change the amount of distance you sent ur packages, the only thing that can be done to solve this issue is by placing the server machine in the Asia Region of the world which would mean the rest of the people in the world would face horrible lag so placing the server in europe with a decent machine is your best bet
