ARM Wrestling: Fedora 17 vs. Ubuntu Linux

The OpenMP efficiency between the tested Ubuntu and Fedora releases was effectively the same.

When running the first really computational test, FFTE, the Fedora 17 cpufreq concerns for the OMAP4460 were confirmed. With Fedora 17 ARM GA running much slower than Ubuntu and the missing cpufreq support, it looks like when using the default kernel the two Cortex A9 cores are running much slower than what they're rated.

Additional computational tests confirmed that Fedora 17 ARM GA on the PandaBoard ES is much slower than Ubuntu 12.04 LTS and Ubuntu 12.10. However, from these tests it is at least nice to see that Xfce 4.8 and Unity were not noticeably affecting the system's performance.
