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. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
