[jira] [Commented] (HADOOP-11540) Raw Reed-Solomon coder using
Intel ISA-L library
[ https://issues.apache.org/jira/browse/HADOOP-11540?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14392409#comment-14392409 ]
Kai Zheng commented on HADOOP-11540:
------------------------------------
I had an initial patch for this. For the rather initial RS coder based on ISA-L, using the benchmark test framework in HADOOP-11588, I got the following results, in my development machine. The speed up is about 20X ! Will test it on serious servers.
