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.

The Debian GNU/kFreeBSD project has been quite interesting as one of the official Debian operating system ports. Debian GNU/kFreeBSD pairs the FreeBSD kernel with the Debian GNU user-land so that users can enjoy their traditional Debian applications while taking advantage of the FreeBSD kernel. With the recently released FreeBSD 9.0 kernel having worked its way into Debian Wheezy, how is the FreeBSD 9.0 kernel performance compared to the Linux 3.2 kernel? This article provides those benchmarks.

For some results that are more interesting than the recent RHEL / Oracle / CentOS / Scientific Linux comparison, here are some benchmarks pitting Red Hat Enterprise Linux 6.2 against a development snapshot of Ubuntu 12.04 LTS on three different systems.

While most x86 hardware shipping in the past few years has been x86_64-capable, Canonical has continued recommending the 32-bit version of Ubuntu Linux over the 64-bit version. With Ubuntu 12.04 LTS "Precise Pangolin" this will hopefully change where the 64-bit version becomes recommended as the default spin. In this article are some updated benchmarks showing the performance of the 32-bit versus 64-bit versions of Ubuntu 12.04 LTS.

Does Red Hat Enterprise Linux perform any better (or worse) than the various "Enterprise Linux" distributions that are derived from RHEL? Now that Scientific Linux 6.2 was released, here is a performance comparison of Red Hat Enterprise Linux, Oracle Linux, CentOS, and Scientific Linux across three different systems.

Regardless of whether you're an Apple fan or not, by now you've likely heard the information about Mac OS X 10.8 "Mountain Lion" that began making its rounds on the Internet since last week. But how's the performance of Mac OS X 10.8 and how will it compare to the competition on the Linux side, namely Ubuntu 12.04 LTS? In this article are our first benchmarks of the developer preview release of Mac OS X 10.8 compared to Mac OS X 10.7.3 and then Ubuntu 11.10 plus the latest Ubuntu 12.04 LTS development snapshot.

In recent weeks I have shown how Ubuntu 12.04 is ARM-ing up for better performance on the ARMv7 architecture by enabling hard-float builds and how the TI OMAP4 support has come together resulting in significant performance gains. Nevertheless, how is modern ARM hardware now comparing to the low-end Intel x86 competition? In this article are some results from Ubuntu 12.04 comparing the ARM performance to some Intel Core, Pentium, and Atom hardware.
