Ubuntu 12.10 Continues Strong On The PandaBoard ES

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.

Mid-2012: Arch Linux vs. Slackware vs. Ubuntu vs. Fedora

At the request of many Phoronix readers following the release of updated Arch Linux media, here are some new Arch Linux benchmarks. However, this is not just Arch vs. Ubuntu, but rather a larger Linux distribution performance comparison. In this article are benchmark results from Ubuntu 12.04 LTS, CentOS 6.2, Fedora 17, Slackware 14.0 Beta, and Arch Linux.

Ubuntu, RHEL, SUSE, Amazon Linux On The Amazon EC2 Cloud

After providing benchmarks last week of Ubuntu 12.04 LTS on different Amazon EC2 instance types, up today are more benchmarks from the Amazon Elastic Compute Cloud. Rather than just tossing out a lot of Amazon EC2 numbers of the different instance types to judge their performance, this article offers benchmarks of different Linux distributions on the same cloud. Tested here are Ubuntu 12.04 LTS, Amazon Linux AMI 2012.03, Red Hat Enterprise Linux 6.3, and SUSE Linux Enterprise Server 11.

The Power Consumption In Ubuntu 12.10

Since last year when spotting a major Linux kernel power regression and subsequently finding the cause of the power problem that affected a large number of mobile Linux users, plus other regressions, it's been fun to look at the Linux power performance situation. How though is the latest Ubuntu Linux code performing when it comes to power efficiency? Here are some early tests of Ubuntu 12.10.

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.
