Red Hat Enterprise Linux 6.2 vs. Ubuntu 12.04 LTS
Phoronix: Red Hat Enterprise Linux 6.2 vs. Ubuntu 12.04 LTS
For some results that are more interesting than the recent RHEL / Oracle / CentOS / Scientific Linux comparison, here are some benchmarks pitting Red Hat Enterprise Linux 6.2 against a development snapshot of Ubuntu 12.04 LTS on three different systems.
does anyone have any insight into the performance differences? gcc versions, compiler settings, file systems, kernel differences, what do you think? I am intrigued.
Totally misread the headline, thought it said Redhat Linux 6.2, not that your article wasn't good but it would have been more interesting to see how well old-school stacked up.

RHEL is supposed to be rock solid and not bleeding edge.
"LTS" is supposed to be rock solid and not bleeding edge, too!

Many of these benchmarks are equivalent and some go to RHEL so apparently newer is not always better.
Again it is far more complex than you make it seem.
RHEL 6.2 is very recent so your age argument is bogus, RedHat backports lots of stuff, esp. performance enhancements

When did that ever happen? *scnr

Wherever my last post went to...
Red Hat does not bump software versions throughout the release cycle. There ist certified software for rhel, which relies on this.
For instance: kernel is 2.6.32, gcc is at 4.4.6 and so on.
Rad Hat backports security fixes, not features! 6.2 is not very "recent", it has the most recent security fixes! Kernel is still 2.6.32 and that wont change. They sometimes include some drivers from future kernels, but nothing more.
So: codebase is from 2010.
You should really not make any more of this comparisons between Red Hat and Ubuntu latest release. First, Red Hat tries to hold the API and ABI for developers and they have to run on something older. Second, you don't want to start a war between Red Hat and Ubuntu cause all the performance Ubuntu has is because of Red Hat developers work...
You should read the RHEL 6.1/6.2 release notes. You will see many 2.6.33 to 3.0 kernel features (and drivers) backported.
