MacOS APFS filesystem performing much better than the dated HFS+

APFS volumes do not use CoreStorage and use filesystem-level encryption instead: you'll notice that because it does not require reboot to turn on encryption anymore.

Since many of us use Full Disk Encryption I'd prefer seeing encrypted FS benchmarks. As per https://news.ycombinator.com/item?id=15333036 it doesn't look so promising:
