[jira] [Commented] (HADOOP-12725) RPC encryption benchmark and
optimization prototypes
[ https://issues.apache.org/jira/browse/HADOOP-12725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16252869#comment-16252869 ]
Konstantin Shvachko commented on HADOOP-12725:
----------------------------------------------
Hey guys I actually ran some benchmarks to measure the performance of encryption for NameNode RPCs.
I jsut used NNThoughputBenchmark, which you can now run against a real NameNode. So I would start a stand-alone NN with different security settings and run NNThroughput from a different machine. Would that be a good enough bechmark? Are you targeting other than NN RPCs here?
BTW the ecnrypted RPC performance was not good, although not 25x either, but definitely worth optimizing.

> This would implement a benchmark tool to measure and compare the performance of Hadoop IPC/RPC call when security is enabled and different SASL QOP(Quality of Protection) is enforced. Given the data collected by this benchmark, it would then be able to know if any performance concern when considering to enforce privacy, integration, or authenticy protection level, and do optimization accordingly.
