August 23, 2012 -- The Linux 3.5 kernel for Texas Instruments OMAP4 devices has finally been uploaded into the Quantal repository for Ubuntu 12.10. With the upgraded kernel release, here are some new benchmarks of the popular PandaBoard ES compared to earlier Ubuntu 12.10 development snapshots, Ubuntu 12.04 LTS, and Ubuntu 11.10 from the dual-core Cortex-A9 ARMv7 development hardware.

August 22, 2012 -- Recently I have shown that Intel graphics hit a high point with the Linux 3.6 kernel and that Ubuntu 12.10 is faster with Intel hardware compared to the current Ubuntu 12.04 LTS release. In this article are more Ubuntu 12.04 LTS vs. Ubuntu 12.10 benchmarks to highlight the performance improvements for Intel Sandy Bridge graphics that will be found in Ubuntu 12.10.

August 14, 2012 -- While benchmarks have already indicated ARM performance improvements in Ubuntu 12.10, early testing of this "Quantal Quetzal" release has also revealed that Intel hardware is benefiting too from performance optimizations for this Linux operating system update due out in October.

August 09, 2012 -- For some workloads, the recently-released Apple OS X 10.8 "Mountain Lion" operating system is faster than its predecessor, OS X 10.8 "Lion". Here are some comparative benchmarks from the Apple MacBook Pro with Retina Display and Intel Ivy Bridge 2.3GHz Core i7 processor.

August 02, 2012 -- 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.

July 31, 2012 -- 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.

July 30, 2012 -- 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.

July 13, 2012 -- For some interesting benchmarks to share before the start of the weekend, here's some recent test results conducted at Phoronix that's comparing Oracle Solaris 11 Express, Ubuntu 12.04 LTS, CentOS 6.2, Debian GNU/kFreeBSD Wheezy, and Fedora 17.

July 11, 2012 -- With Debian Wheezy now frozen for its release sometime next year, here are some early benchmarks comparing the performance of Debian 6.0.5 "Squeeze" to the latest packages for the Debian 7.0 "Wheezy" release. For this Squeeze vs. Wheezy comparison, both Debian GNU/Linux and Debian GNU/kFreeBSD were benchmarked from an Intel 64-bit system.

July 05, 2012 -- 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.
