November 30, 2012 -- With Linux 4 Tegra R16 now having an Ubuntu 12.04 LTS (hardfp) sample file-system and the R16 drivers supporting ARM hard floating-point as the preferred format over softfp, new Tegra 3 "Cardhu" tablet benchmarks were carried out to look at the performance between L4T R16 + Ubuntu 12.04 vs. L4T R15 + Ubuntu 11.04.

November 28, 2012 -- In preparation for the imminent release of Phoronix Test Suite 4.2-Randaberg, final validation testing was done on a variety of Linux operating systems in Amazon's EC2 compute cloud. Many of the official Linux images were benchmarked from the c1.xlarge High-CPU Extra Large Instance, including Amazon Linux AMI 2012.09, Red Hat Enterprise Linux 6.3, Ubuntu 11.10, Ubuntu 12.04.1 LTS, and SUSE Linux Enterprise 11.

November 17, 2012 -- At the beginning of this month there was the release of DragonFlyBSD 3.2.1 that claimed a battle for speed against Linux with major improvements for the multi-threaded application performance against Linux. PostgreSQL was the only benchmark cited by the DragonFly camp with the new performance results, so a couple Phoronix tests were carried out.

October 22, 2012 -- For kicking off a new week of Linux benchmarks, here are some results of a high-end Intel Extreme Edition workstation when comparing the bare metal host and KVM virtualization performance between Ubuntu 12.10 and the earlier Ubuntu 12.04.1 LTS release and then the RHEL-based CentOS 6.3.

October 19, 2012 -- For those wondering about the performance of Ubuntu Linux 12.10 versus Microsoft Windows 7 when using the same system and the Catalyst graphics driver, here are new Phoronix benchmarks of an AMD Radeon HD 6870 graphics card when running a variety of OpenGL workloads from Ubuntu 12.10, Kubuntu 12.10 (the KDE desktop version of Ubuntu 12.10 to avoid the Unity desktop overhead), and Microsoft Windows 7 Professional x64.

October 14, 2012 -- In past years on Phoronix there has been no shortage of 32-bit vs. 64-bit Linux benchmarks. Assuming you don't have a limited amount of RAM and under memory pressure, 64-bit distributions tend to be much faster than the 32-bit versions. However, some Linux users still often wonder whether they should use the 32-bit or 64-bit version of their distribution even when on 64-bit hardware. So with that said, here's some more 32-bit vs. 64-bit benchmarks of Ubuntu 12.10 with the Linux 3.5 kernel.

October 11, 2012 -- When Ubuntu 12.10 "Quantal Quetzal" is officially released there will be more Ubuntu 12.10 performance figures to publish beyond what's already been benchmarked. In this article are a preview of some Intel performance figures comparing an updated Ubuntu 12.04.1 LTS installation to Ubuntu 12.10 with its near-final packages as of this week.

October 09, 2012 -- While the Linux 3.7-rc1 kernel has not even been released yet, most of the feature pulls have now made their way into the mainline Linux kernel tree. Here are some of the first benchmarks of the Linux 3.7 kernel to see if anything has changed for the Intel x86_64 Linux performance with this very exciting kernel.

October 07, 2012 -- While LLVMpipe may be a different story, when using hardware-accelerated graphics drivers with the recently released Unity 6.8 desktop, the performance doesn't change much. For at least one driver, there's even a new OpenGL performance regression under certain workloads. Here's some test results of Unity 6.6 vs. Unity 6.8 on the Radeon and Nouveau drivers.

September 29, 2012 -- With the recent release of the Unity 6.6 desktop for Ubuntu 12.10 Beta 2, benchmarks were done to see how the OpenGL gaming performance compares to that of Unity 6.4 from the earlier beta state of the Quantal Quetzal, plus the respective Compiz versions. At least for Intel Ivy Bridge graphics under some workloads, it looks like the Unity/Compiz updates are slowing down the GL performance even further.
