This is just memory openssl speed. There i'm getting 600-700MB/s:
The 'numbers' are in 1000s of bytes per second processed.
type             16 bytes     64 bytes    256 bytes   1024 bytes   8192 
bytes
aes-128-cbc     648664.33k   688924.90k   695855.45k   700784.64k 
704027.06k

But scp / ssh just boosts from 42MB/s to 76Mb/s.
