UE4 not using all cores when compiling project
So I just upgraded to a Threadripper 1950x and while compiling the engine uses all my cores, compiling my project in the engine doesn't which makes for very slow iteration times.
Is there anyway for me to force ue4 to use all my cores?

I found that converting my project to IWYU and setting the bUseUnityBuild to false, MinFilesUsingPrecompiledHeader to 1 and ProcessorCountMultiplier to 2 in the BuildConfiguration.xml fixed the issue of using all cores. Iteration times are still not as fast as I expected it to be still taking around 5 to 30 secs depending on how much code changed, but its not unbearable, if any one has any idea of how to speed up iteration times please tell me, thanks.
