In the days ahead we will have benchmarks of Ubuntu 12.04 LTS against Oracle Linux 6.5 and 7.0 Beta 1 along with CentOS 6.5 and the RHEL 7 release candidate among other enterprise-oriented Linux distributions. For this article to end out the weekend are just some benchmarks of Oracle Linux 6.5 vs. 7.0 Beta 1 when tested from the same hardware -- an Intel Core i7 3960X Ivy Bridge Extreme Edition system with a total of 12 logical CPU threads.
Like upstream Red Hat Enterprise Linux 7, Oracle Linux 7 is also using the GNOME Shell 3.8 desktop environment. XFS is also the default file-system in place of EXT4 from RHEL/Oracle Linux 6.
Similar to upstream RHEL7, Oracle Linux 7.0 Beta 1 is shipping with a RHEL7-compatible Linux 3.10 kernel, X.Org Server 1.15 RC1, Mesa 9.2.2, and the GCC 4.8.2 compiler.
With Oracle Linux 6.5 having GCC 4.4.7 by default, going to Oracle Linux 7 means a performance improvement for many built-from-source, performance-sensitive workloads thanks to the improvements within the GNU Compiler Collection in recent years.
The PostMark disk performance was slightly faster in Oracle Linux 7 using XFS over EXT4 in Oracle Linux 6.5.
GCC 4.8 is responsible for yielding most of the performance improvements out of this round of Oracle Linux 6.5 vs. 7.0 Beta 1 performance testing. While by default a Linux 3.10 EL7-compatible kernel is used, Oracle Linux 7.0 Beta 1 has a 3.8-based kernel that contains Oracle's "Unbreakable Enterprise Kernel" patches.
See more of our early Oracle Linux 7.0 open-source benchmarks done via the Phoronix Test Suite at 1404208-KH-ORACLE76L05. Again, in the days ahead will be more thorough testing with multiple enterprise-grade Linux distributions. Have other test requests? Let us know via Phoronix on Facebook, Google+, or Twitter.
