The latest ARM Linux benchmarks to share at Phoronix is a comparison of Ubuntu 12.10, Linaro 12.10, Fedora 17, and Arch Linux when running from the dual-core Cortex-A9 OMAP4460-based PandaBoard ES development board.
There's no shortage of PandaBoard benchmarks on Phoronix with these being wonderful ARM Linux development boards that are widely supported by many Linux distributions that are targeting ARMv7 images and the performance for the dual-core 1.2GHz processor is decent. With the recent releases of Ubuntu 12.10 and Linaro 12.10 along with Arch Linux continuing to roll along, updated benchmarks from the PandaBoard ES were carried out.
Benchmarks from the four Linux distributions were carried out in their stock configurations. Unfortunately, the openSUSE 12.2 ARM release wasn't ready at the time that this round of benchmarking was carried out. All benchmarking was handled via the Phoronix Test Suite.
