BTW, do you plan to MFC this as well ? Results at the bottom of http://www.tancsa.com/fpu.html It certainly makes a difference with geli. IPSEC and userland stuff, not so much. The CPU itself is crazy fast, so its hard to see a difference in things like ssh and even ipsec didnt yield any differences. For ssh and userland stuff I guess once there is an aesni userland engine, this would probably help over the cryptodev interface. ---Mike
