For those that were interested by the CompuLab Trim-Slice, a desktop built around the ARM-based NVIDIA Tegra 2 platform, here are some more benchmarks. This time the numbers are looking at the performance of the dual-core ARM Cortex A9 system when using the Ubuntu 11.04, 11.10, and 12.04 packages.
As mentioned in earlier articles, Ubuntu 11.04 is the operating system that ships by default on the CompuLab Trim-Slice, but the ARM system isn't locked down by any measures and users are free to install whatever operating system they wish. In this benchmarking of the Trim-Slice the user-spaces of Ubuntu 11.04, 11.10, and the latest 12.04 development packages are being compared. The Linux kernel throughout this process remained using CompuLab's spin of the Linux 2.6.38, so this mostly comes down to comparing the compiler differences and other user-land changes between the last three release cycles of Ubuntu Linux.
