It doesn't be a matter and as you might know the network bandwidth doesn't help to play the game at the international game server. :-) However what ping do you get with or without Mudfish?

Did you try to change a mudfish node based on FAQ - Nodes section for your game item? If you're using the advanced mode, please start with the basic mode.
