Subject [jira] [Commented] (HDFS-11814) Benchmark and tune for prefered default cell size
Date Mon, 07 Aug 2017 08:03:00 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11814?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16116214#comment-16116214

Wei Zhou commented on HDFS-11814:
---------------------------------

I did some performance testing on EC IO performance with different EC schema and cell size,
ISA-L library is used in the testing.
{{TestDFSIO}} used to test read/write performance, the following two parameters used for testing.
{{-nrFiles 1  -size 10GB}}

Overall execution time is used for comparison:

Cluster hardware configuration:
CPU: 2 Sockect, Xeon E5-2699 v3 @ 2.30GHz
Memory: 256GB
Storage: Seagate Momentus 7200.5 ST9750420AS, HDD, 7 disks per node
Network: 1000Mb/s
OS: CentOS 7.2

Thanks!
