As shared on Phoronix in many articles already, Canonical has big plans for Ubuntu in the ARM-space. They are looking forward to making Ubuntu Linux be the first operating system to support the forthcoming ARM Cortex A15, but before that and the other achievements they have planned, they must first ship Ubuntu 12.04 LTS.
With Ubuntu 12.04 there is already some exciting improvements on the ARM front, including ARM hard-float support, better OMAP4 support, and other packaging improvements. In this article are some early benchmarks of Ubuntu 12.04 LTS "Precise Pangolin" from the PandaBoard ES. For some workloads, Ubuntu 12.04 is remarkably faster than Ubuntu 11.10.
It was back in December that I began benchmarking the PandaBoard ES, a development board based around the Texas Instruments OMAP4660. The OMAP4660 PandaBoard ES packs a dual-core ARM Cortex-A9 with each core being able to run up to 1.2GHz, 1080p video support with its PowerVR SGX540 graphics core that is capable of OpenGL ES 2.0/1.1 and OpenGL 1.1 acceleration, 1GB of low-power DDR2 RAM, 10/100 Ethernet, and two USB 2.0 ports. The original PandaBoard is based around the slightly older OMAP4430 SoC that is still a dual-core ARM Cortex-A9 part but only runs up to 1.0GHz in speed.
