I am looking at upgrading to RHEL 7 or 6.6 but before getting there i
want to see if the existing version works fine. If it works then i am
good but if it does not then i will have to upgrade to newer versions.
You have to test on the system you intend to run in production later or
your results are useless. Simply upgrading to 7 might already give you a
big boost in performance simply because the virtualization components
are *much* more up-to-date.
The qemu/kvm components - the heart of the virtualization - on RHEL 5
are positively ancient so I would not expect to get any decent numbers
compared to todays standards.
