Warcraft 3 MODs

Hi,

I've got a question about using War3 FT. I've tried searching and it appears War3 XP has the option in the config to simply turn on or off "FastXP", however in War3 FT I can see an option to change the modifier, and whether or not to save xp.

Anyway's, I want my server to run as a Fast XP server, but not sure what to change the modifier, or whether if I simply disable the savexp option, it automatically adjust's the amount of XP gained.

Any help will be appreciated,

Thanks
