Unreal Tournament has a variable that can be set in UnrealTournament.ini which controls the total number of ports used at once to ping. The default is 10, but depending on your system and Internet connection you can increase this number to your heart's content. You should probably keep it at or under 40 unless you know what you are doing.

The default is 10 but you can set whatever you are comfortable with. 15 is 50% faster, 20 is 100% faster, but be sure you know your system and network limits. I use 20 and it is much faster.
