Increasing compile time in unreal

Hello friends,

I am using unreal 4.8.When i edit one single cpp file it takes 30 to 40 seconds to compile.I don’t know how to increase the compile time speed in windows 7.I refereed this link but it doesn’t provide me much info.It says i have to edit BuildConfiguration.cs but i can’t find that cs file i only see BuildConfiguration.xml in unreal installed folder.Can somebody tell me the process for increasing compile time in ue 4.8.

Thanks,
