Now that the release candidate to Red Hat Enterprise Linux 7.0 is publicly available, here are the initial benchmarks of RHEL 7.0 RC compared to Oracle Linux, CentOS, and Fedora Linux.
The tests in this article are just some preliminary performance figures compared to major enterprise Linux distributions from an Intel Core i7 4960X Extreme Edition system that was available at the time of testing. The distributions included:
Oracle Linux 6.5 - Oracle's spin of the Red Hat Enterprise Linux 6.5 source tree.
Oracle Linux 7.0 Beta 1 - Oracle's spin of the earlier RHEL 7.0 Beta 1 source code.
CentOS 6.5 - The community spin of RHEL 6.5 that is now collaborating with upstream Red Hat Enterprise Linux.
Fedora 20 - The out-of-the-box Fedora 20 for the latest experience of the Red Hat sponsored distribution
RHEL 7.0 RC1 - The just-released public ISO of the new Red Hat Enterprise Linux 7.0 environment.
Sadly due to lacking an official license from RHEL for performance testing is no official performance comparison against RHEL 6.5, but the CentOS 6.5 numbers should be rather comparable.
Key information to point out about the Red Hat Enterprise Linux 7.0 release candidate is the Linux 3.10 kernel, GNOME Shell 3.8.4, X.Org Server 1.15.0, Mesa 9.2.5, GCC 4.8.2, and the XFS file-system is used by default.
All of this enterprise Linux benchmarking was handled in a fully standardized and completely automated and reproducible manner using the open-source Phoronix Test Suite benchmarking software. Comparisons of RHEL against non-Red-Hat distributions will be upcoming in the days ahead... In extension of the multi-way Linux distribution comparison from a few days ago.
