ARM Wrestling: Fedora 17 vs. Ubuntu Linux

When it comes to operating systems for the TI OMAP4 PandaBoard and PandaBoard ES, Ubuntu Linux is usually the winner for several reasons. However, with last month's release of Fedora 17 for ARM, how is the Red Hat sponsored distribution running on these ARM development boards? Here's an overview of my experiences when running the latest Ubuntu and Fedora releases on the ARM Cortex A9 development hardware along with Arch Linux. There are also benchmarks comparing the ARM Linux performance.

Intel Atom N270 Still Sees Some Gains On Linux

While the N270, Intel's first-generation Atom processor for netbooks, is over four years old, the performance of this low-power CPU that wound up being found in a lot of netbook/nettops continues to improve under Linux -- well, sans a few regressions. Here are some benchmarks highlighting the performance changes when going from Ubuntu 10.04.4 LTS to Ubuntu 12.04 LTS and then lastly a development snapshot of the forthcoming Ubuntu 12.10.

Ubuntu 12.04 LTS ARMv7 Linux Performance Gains

Earlier in the Ubuntu 12.04 LTS "Precise Pangolin" development cycle I noted some performance improvements happening on the ARM side, particularly for Texas Instruments OMAP4. Namely, Ubuntu 12.04 was ARMing up for better performance with ARM hard-float support and the performance becoming more compelling for the PandaBoard ES hardware with proper cpufreq support. In this article is a comparison of the Ubuntu 11.10 and Ubuntu 12.04 ARM performance.
