Subject [jira] Updated: (CHUKWA-583) Copying data from inputStream to OuputStream needs appropriate buffer size
Date Sun, 13 Mar 2011 04:11:59 GMT

     [ https://issues.apache.org/jira/browse/CHUKWA-583?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Ari Rabkin updated CHUKWA-583:
------------------------------

    Priority: Trivial  (was: Major)

This looks like an autogenerated bug report. I would caution you against this.  The code you're
flagging is in the test suite. It is NOT performance critical, nor is it run on substantial
data volumes. It's probably pointless to change. The human time invested in generating and
committing a patch is probably more than the "fix" would ever save.

  line: 54-58
> In the function copyFile, the buffer size is fixed as 4096 bytes. With the size of the
data varies, the performance can be damaged a lot.
> We need an appropriate buffer size which depends on the size of the data to be copied.

> This is the same as the Appache Bug (https://issues.apache.org/bugzilla/show_bug.cgi?id=32546)
