Subject [jira] [Commented] (HDFS-4551) Change WebHDFS buffersize behavior to improve default performance
Date Thu, 07 Mar 2013 03:08:14 GMT

    [ https://issues.apache.org/jira/browse/HDFS-4551?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13595491#comment-13595491

Tsz Wo (Nicholas), SZE commented on HDFS-4551:

Then, how is the performance of 4KB?  Is it similar to 64KB?  If not, we probably should increase
the value.  Could you check it?  Thank you in advance!

This causes performance problems if that buffersize is large.
