It depends of the size of the data to crypt ; with the Geode crypto device there is an improvement (from 3 MBytes to 5 MB) using sftp or scp. And the load is very lower than with software crypto. Same if you use "openssl enc". The benefit starts with a block around 256 octets. IMHO the Geode LX is slow.
