Yeah, but cryptosoft is calling into cryptoapi to do the actual crypto.
So basically this is an in kernel benchmark of the OCF API using only the
in kernel cryptoapi to do software based encrption across all 8 cores.
In theory this is how fast ipsec could go if klips added no overhead.
I think this should be goood enough to comfortably get us to 1Gbps of
ipsec throughput. Only a real test will tell, SMP performance is fickle and
any misbehaviour with klips could blow this out. It will be good to see
the real ipsec results, for better or worse :-)
