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.
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.
When it comes to operating systems for the TI OMAP4 PandaBoard and PandaBoard ES, Ubuntu Linux is usually the winner for several reasons. However, with last month's release of Fedora 17 for ARM, how is the Red Hat sponsored distribution running on these ARM development boards? Here's an overview of my experiences when running the latest Ubuntu and Fedora releases on the ARM Cortex A9 development hardware along with Arch Linux. There are also benchmarks comparing the ARM Linux performance.
While the N270, Intel's first-generation Atom processor for netbooks, is over four years old, the performance of this low-power CPU that wound up being found in a lot of netbook/nettops continues to improve under Linux -- well, sans a few regressions. Here are some benchmarks highlighting the performance changes when going from Ubuntu 10.04.4 LTS to Ubuntu 12.04 LTS and then lastly a development snapshot of the forthcoming Ubuntu 12.10.
As the latest tests of Fedora 17 vs. Ubuntu 12.04 LTS, here are benchmarks comparing the performance of an Intel Core i7 "Ivy Bridge" system on the two distributions named Beefy Miracle and Precise Pangolin, respectively.
With Debian 7.0 "Wheezy" set to be frozen soon, I took the opportunity to run some new benchmarks of Debian GNU/kFreeBSD, the Debian OS variant using the FreeBSD kernel rather than Linux, to compare it to Debian GNU/Linux as well as Ubuntu Linux and PC-BSD/FreeBSD 9.0.
While there's still over three months to go until Ubuntu 12.10 "Quantal Quetzal" will be officially released, for many computers this release will be faster than its predecessor, Ubuntu 12.04 LTS.
Before Apple releases Mac OS X 10.8 "Mountain Lion" next month, here's a look at how the latest point release of Mac OS X 10.7 "Lion" is performing compared to Ubuntu 12.04 LTS "Precise Pangolin" and the latest development snapshot of Ubuntu 12.10 "Quantal Quetzal" Linux.
Last week I shared how the open-source R500 driver can compete with the legacy Catalyst Linux driver on an old Intel laptop with ATI graphics, but how has the performance for other areas of the system changed with the latest Ubuntu Linux code? In this article are benchmarks from other areas of this Core Duo laptop when running Ubuntu 8.04.4 LTS, Ubuntu 12.04 LTS, and then a recent development snapshot of Ubuntu 12.10.
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.
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.
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.
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.
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.
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.
If you want to try out FreeBSD 9.0 this holiday but are not turned on by the actual FreeBSD 9.0 install and setup process, nor find the KDE desktop of PC-BSD 9.0 enjoyable, you may want to try out GhostBSD 2.5.
