In this post, we look into why IPlatformFileCreateDirectory() was responsible for nearly 1 million allocations during a full cook of KiteDemo and why FPaths::IsDrive(), a huge 100-line function, is being used just to determine whether a filepath begins with a drive mapping... all for the purpose of further speeding up Unreal's cook process just a little bit more

UE4's Package Versioning is a bit of a dark art for most.. here we try to remove some of the confusion around it - while, again, offering some improvements through optimization

We present here a way to improve cook times by reducing the frequency of garbage collection
