Comment 2 RHEL Program Management 2012-07-31 07:10:46 UTC
This request was evaluated by Red Hat Product Management for
inclusion in the current release of Red Hat Enterprise Linux.
Because the affected component is not scheduled to be updated in the
current release, Red Hat is unfortunately unable to address this
request at this time. Red Hat invites you to ask your support
representative to propose this request, if appropriate and relevant,
in the next release of Red Hat Enterprise Linux.

it will be very useful to compare performance between the previous version of viostor from rhl6.2 and the most recent one from rhel6.3 on rhel6.3 platform.

Does you want to get the compare result of virtio-win-1.4.0-1.el6 vs virtio-win-1.5.3-1.el6_3 on rhel6.3 host ?

Right, I believe it will help us to narrow down the problem.

Thank you,
Vadim.

Defering to 5.10 since we decided not to use the RHEL6 drivers in 5.9, and the degradation is in those drivers.

Comment 10 RHEL Program Management 2013-03-27 13:56:20 UTC
Development Management has reviewed and declined this request.
You may appeal this decision by reopening this request.
