Kai Zheng commented on HADOOP-12725:
------------------------------------

Good update, [~zhouwei]! Maybe we could also have a bench test for the GSSAPI layer, so that
we can compare and know the overhead incurred by the SASL layer? Thanks.

> 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.
