While Ubuntu 12.04 already did a very good job at enhancing the ARM performance, Ubuntu 12.10 already has a number of performance improvements for ARM devices.

For those curious about the performance changes for Intel Sandy Bridge hardware when moving from Ubuntu 11.10 to Ubuntu 12.04, here is a quick overview.
Earlier in the Ubuntu 12.04 LTS "Precise Pangolin" development cycle I noted some performance improvements happening on the ARM side, particularly for Texas Instruments OMAP4. Namely, Ubuntu 12.04 was ARMing up for better performance with ARM hard-float support and the performance becoming more compelling for the PandaBoard ES hardware with proper cpufreq support. In this article is a comparison of the Ubuntu 11.10 and Ubuntu 12.04 ARM performance.

For the past few days I have been trying out the Microsoft Windows 8 Consumer Preview. For the most part, I would call Windows 8 a crap wreck, but it is not without a few advantages over Linux.
Here's a comparison of the Ubuntu 12.04 LTS versus Microsoft Windows 7 performance when it comes to using Intel Sandy Bridge and Ivy Bridge processors with integrated graphics. While the Sandy Bridge graphics performance was once faster when it came to OpenGL with the open-source Linux driver, that's no longer the case. The Linux OpenGL performance for both Sandy Bridge and Ivy Bridge hardware is now slower in most GL workloads than Intel's Windows 7 x64 driver.

How does the choice of desktop environments you make for Ubuntu 12.04 LTS impact your system's performance and power consumption? Here's the latest round of benchmarking from the various Ubuntu 12.04 desktop environment choices -- Unity, Unity 2D, GNOME Shell, KDE, Xfce, LXDE, and Openbox -- when running them on three different laptops.

While recent testing has shown how Ubuntu 12.04 LTS KVM/Xen/VirtualBox virtualization compares between Intel's Sandy Bridge and AMD's Bulldozer platforms, in this article is a different look at the KVM virtualization performance of the forthcoming Ubuntu 12.04 LTS operating system. In this review is a look at the KVM virtualization performance of Ubuntu 12.04 LTS compared to the earlier Ubuntu 10.04.4 and Ubuntu 8.04.4 Long-Term Support releases.

Similar to the mixed boot performance results for Ubuntu 12.04, the power consumption results are also mixed. For some hardware, Ubuntu 12.04 is the most power efficient Ubuntu Linux release in recent history while for some other hardware the Precise Pangolin is continuing in a power binge.

Ubuntu 12.04 LTS "Precise Pangolin" can boot faster... sometimes. If you are not lucky, Ubuntu 12.04 LTS can boot more than twice as slow as Ubuntu 10.04, the previous LTS release. Here are boot performance results of Ubuntu 12.04 LTS running on six distinct notebooks and comparing the Bootchart results upon clean installations of Ubuntu Linux going back as far as six years from the days of the Ubuntu 6.06 LTS "Dapper Drake" release.
Curious to know how the performance of enterprise Linux (RHEL, CentOS, Scientific, etc) evolves over time? Here's a look at the performance of Scientific Linux 5.7, the recently released Scientific Linux 6.2, and then Fedora 16 as representative of what will eventually work its way into Red Hat Enterprise Linux 7.
