> Optimize Hadoop RPC encryption performance.pdf
>
>
> 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.
