With the disk-focused PostMark benchmark, Ubuntu 13.10 with the EXT4 file-system was tied in first with Oracle Linux 7.0 Beta 1, which is using the XFS file-system as with Red Hat Enterprise Linux 7. The EXT4 performance seems to have dropped back on Ubuntu 14.04 LTS for this single-disk HDD-based system by a measurable margin. Ubuntu 14.04 LTS was the slowest when running PostMark while CentOS 6.5, openSUSE 13.1, Oracle Linux 6.5, and Ubuntu 12.04.4 LTS were performance close to one another.

For many built-from-source benchmarks, there was little change between these recent Linux distribution releases.

However, for some benchmarks where the GNU Compiler Collection (GCC) has seen performance tuning in recent releases, the newer Linux distributions are running faster compared to the existing stable enterprise Linux distributions on their old GCC compiler releases. For Parboil's OpenMP MRI-Q test, the GCC 4.8-based distributions were significantly faster than the older round of enterprise Linux distributions.
