Ben Marsh	6f57983b93	UBT: When building a target, start prefetching the contents of engine/project/plugin source folders in parallel on background threads as soon as UBT starts up (by instantiating FileItem and DirectoryItem objects). This reduces I/O waits on the main thread when validating the contents of the makefile or building a target. Measured ~20% reduction in UBT times when using a makefile. ... Other directories are probably worth prefetching too; needs measuring. #rb none [CL 4673733 by Ben Marsh in Dev-Build branch]	2018-12-23 20:29:48 -05:00
