Wei Zhou commented on HADOOP-12725:
-----------------------------------
I did a benchmark test, comparing the performance between encryption and no
encryption.
Test environment: JDK 1.7u65
Encryption: GSSAPI AES128 Cipher provided in sun.crypto.provider.AESCrypt by
default
Packet size: 5MB
Run times: 100 rounds
Without encryption: total execution time 561ms
With encryption: 14471ms
It can be seen that encryption of QOP incurs overhead 25X.
We will investigate how to optimize it. 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.
