Back in June I showed how Ubuntu 12.10 was continuing to improve the ARM Linux performance and since then showed that on TI OMAP4 hardware Ubuntu is faster than Fedora, while today I have more benchmarks to share. Up now are the latest PandaBoard ES benchmarks from a more recent Ubuntu 12.10 development build for the ARMv7 Cortex-A9 dual-core development board.
The results in this article build upon the results from earlier PandaBoard ES benchmarking on Phoronix to show the performance of Ubuntu 11.10, Ubuntu 12.04 LTS, the earlier Ubuntu 12.10 benchmarks from the beginning of June, and then Ubuntu 12.10 benchmarks using a development build from the end of July.
The OMAP4 media for Ubuntu 12.10 continues to work well, albeit they are still on the Linux 3.4 kernel rather than the Linux 3.5 kernel like in the x86 flavor of Ubuntu 12.10 Quantal. Developers are in the process of moving the OMAP4 kernel to the Linux 3.5 kernel, but are not there quite yet. The good news is that even still on the Linux 3.4 kernel there have been some improvements since the beginning of June. With this latest build, the OMAP DRM driver is finally mode-setting correctly for HDMI to a 1920 x 1200 panel -- the first time it's mode-set to this native resolution for an Acer panel. There are also other subtle enhancements in the latest Ubuntu 12.10 build.
As usual, the Ubuntu 12.10 2012-07-27 installation was left in its stock configuration and packages. Let's see these latest Ubuntu ARMv7 Linux performance results via the Phoronix Test Suite.
