Subject [jira] [Commented] (HADOOP-7824) Native IO uses wrong constants almost everywhere
Date Thu, 28 Jun 2012 01:38:43 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7824?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13402766#comment-13402766
] 

Allen Wittenauer commented on HADOOP-7824:
------------------------------------------

I suspect that's going to be a lot slower.  The C compiler should be able to optimize the
heck out of pre-generated code rather than doing it on the fly. Given that the whole reason
why this code exists is speed....
