Subject [jira] [Commented] (YARN-4081) Add support for multiple resource types in the Resource class
Date Mon, 31 Aug 2015 14:21:46 GMT

    [ https://issues.apache.org/jira/browse/YARN-4081?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14723459#comment-14723459
] 

Varun Vasudev commented on YARN-4081:
-------------------------------------

So I ran a benchmark for the Resource.newInstance call using the Apache jmh framework.

The current implementation returned a performance of 0.033 ±(99.9%) 0.003 ops/ns [Average]
The Map based implementation returned a performance of 0.005 ±(99.9%) 0.001 ops/ns [Average]

So a significant drop but that still translates to being able to create 5M Resource objects
per second per thread(the test was run in a single thread). This was on my MacBookPro(i7-2.3G).
I'm unsure of how to test the GC performance.
