Comment 3 Vadim Rozenfeld 2011-12-09 11:39:13 UTC 
Moving this bug to rhel-6.4.0.
I don't believe we will have enough time
to do some serious optimization in rhel-6.3.0
time frame.
Comment 10 Vadim Rozenfeld 2013-09-08 06:00:05 UTC 
please re-check with build 69 available at https://brewweb.devel.redhat.com/buildinfo?buildID=293655
I would like to close this bug if the results are the same as shown in comment #9, because we will not get better performance in 6.5 

Thanks
Vadim.

Hi, Vadim

    Could we set the bug to verified status and open new bug in 6.6 to track the issue described in comment #11, or what better suggestions to handle the bug?

Thanks
Xiaomei
