Subject [jira] [Commented] (HADOOP-12725) RPC call benchmark and optimization in different SASL QOP level
Date Wed, 27 Jan 2016 08:15:40 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-12725?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15118841#comment-15118841

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.
