BTW, do you plan to MFC this as well ? Sure, I will merge aesni(4), it was the only reason to work on the kern_fpu in stable/8. I want some pause between KPI and driver MFC, to ease the handling of possible mismerge or fixing latent bugs (since stable has much larger testing base then HEAD). >=20 > Results at the bottom of http://www.tancsa.com/fpu.html >=20 > It certainly makes a difference with geli.

Yes, the small blocks encoding/decoding has a large overhead of loop setup code.
