Ubuntu 12.04 LTS KVM Virtualization Battles 8.04.4, 10.04.4 LTS

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.

Ubuntu 12.04 Is A Mixed Power Story

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.

If You're Lucky, Ubuntu 12.04 LTS Can Boot Faster

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.

The Evolution Of Enterprise Linux Performance

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.

Debian: kFreeBSD 9.0 Kernel Competing Against Linux 3.2

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.

Ubuntu 12.04 LTS: 32-bit vs. 64-bit Performance

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.

Red Hat Enterprise Linux 6.2 vs. Its Derivatives

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.

Mac OS X 10.8 vs. Ubuntu 12.04 LTS Performance

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.

ARM On Ubuntu 12.04 LTS Battling Intel x86?

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.

A First Look At The Ubuntu 12.04 Performance

While there's still two months left until Ubuntu 12.04 LTS "Precise Pangolin" will be officially released, here are the first benchmarks of this forthcoming long-term support release. Included are desktop and workstation benchmarks along with a look at the boot performance and power consumption. The Ubuntu 12.04 LTS releases are compared to earlier Ubuntu Linux releases going back to the 10.10 release.

Ubuntu 12.04 ARM Performance Becomes Very Compelling

Last week I delivered benchmarks showing how Ubuntu 12.04 is ARM-ing up for better performance with ARM-based hardware and detailed some of the plans Canonical has for this architecture going forward. While those benchmarks last week illustrated some significant performance improvements with the Ubuntu 12.04 stack -- in large part due to the switch to hard floating-point support -- the gains are not over. In fact, there are already some striking improvements if using the Texas Instruments OMAP4460 SoC as found on the PandaBoard ES.

Ubuntu 11.10 vs. Mac OS X 10.7.2 Performance

After delivering benchmarks last week that were comparing the Intel Sandy Bridge performance of Mac OS X 10.7 "Lion" vs. Ubuntu 11.10 "Oneiric Ocelot" when it came to the Sandy Bridge OpenGL graphics performance, here's a comparative look at the performance of Ubuntu 11.10 against Mac OS X 10.7.2 from the Intel Sandy Bridge-based Mac.

Ubuntu 12.04 Is ARM-ing Up For Better Performance

As shared on Phoronix in many articles already, Canonical has big plans for Ubuntu in the ARM-space. They are looking forward to making Ubuntu Linux be the first operating system to support the forthcoming ARM Cortex A15, but before that and the other achievements they have planned, they must first ship Ubuntu 12.04 LTS. With Ubuntu 12.04 there is already some exciting improvements on the ARM front, including ARM hard-float support, better OMAP4 support, and other packaging improvements. In this article are some early benchmarks of Ubuntu 12.04 LTS "Precise Pangolin" from the PandaBoard ES. For some workloads, Ubuntu 12.04 is remarkably faster than Ubuntu 11.10.

Sabayon 7 vs. Ubuntu 11.10 Performance

The release of Ubuntu 11.10 "Oneiric Ocelot" this week captured most of the Linux spotlight, but also arriving this week was Sabayon 7, the Gentoo-based Linux distribution that's meant to be easy-to-use and desktop-oriented. In this article Sabayon 7 has been pitted against Ubuntu 11.10 with its stock Linux 3.0 kernel and its new experimental Fusion kernel.

The Other Issue With Ubuntu 11.10: Boot Speed

Besides Ubuntu 11.10 "Oneiric Ocelot" continuing to regress when it comes to increased power usage for many different systems, another area where Ubuntu 11.10 has regressed is with its boot speed. A clean install of Ubuntu 11.10 is definitively slower than previous Ubuntu Linux releases. Here's another look at the Ubuntu Oneiric boot performance along with some other new metrics to share as the official Ubuntu 11.10 release approaches later in the week.

WattOS: Is It Faster & Can Save Power Over Ubuntu?

For some months I've been meaning to try out WattOS, an Ubuntu derivative that claims to do more than providing simple desktop theme changes and other high-level customizations. It seeks to provide a simple and fast desktop that's also said to conserve more power and run better on older hardware, but is this actually the case? Here are benchmarks of WattOS R4 compared to the upstream Ubuntu 11.04 release from which it's derived, and the numbers are quite revealing.
