> Hadoop RPC encryption is enabled by setting {{hadoop.rpc.protection}} to "privacy". It utilized SASL {{GSSAPI}} and {{DIGEST-MD5}} mechanisms for secure authentication and data protection. Even {{GSSAPI}} supports using AES, but without AES-NI support by default, so the encryption is slow and will become bottleneck.
> After discuss with [~atm], [~tucu00] and [~umamaheswararao], we can do the same optimization as in HDFS-6606. Use AES-NI with more than *20x* speedup.
> On the other hand, RPC message is small, but RPC is frequent and there may be lots of RPC calls in one connection, we needs to setup benchmark to see real improvement and then make a trade-off.
