I know; apple did that in their Demo.Despite benchmarks APFS has a number of terrific optimizations.
Not limited to but including copying file headers instead of the files themselves, meaning if you’re making two copies of large files they copy instantly instead of the size * time / size.
So with a 4.713 GB file copy on HFS+ it would take you 10 seconds, on APFS it would
be instantaneous. (try copying a large file twice on your desktop)
