[jira] [Commented] (HDFS-8425) [umbrella] Performance tuning and
bug fixing for system tests for EC feature
[ https://issues.apache.org/jira/browse/HDFS-8425?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14568676#comment-14568676 ]
Kai Zheng commented on HDFS-8425:
---------------------------------
Just uploaded a simple performance test report in HADOOP-11540 comparing the native coder based on Intel ISA-L with the Java coder, and we can see that the performance gain can be from 10X up to 35X. Hope this can resolve the performance overhead. Sure we need to optimize and tune further after the basic codes ready.
