FileVault 2 performance issue?

[SquinklePhoom]

Ah yes, that could explain it. From the 1080ti benchmark:
Speed.#1.........: 90098 H/s (255.27ms) @ Accel:512 Loops:128 Thr:256 Vec:1

And from the hashcat output im seeing Accel:32 Loops:16 Thr:640 - not sure about iterations.

Thanks for the quick reply :-)
