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.
When Ubuntu 11.04 was released, Phoronix provided Bootchart results for five different systems showing the boot performance from Ubuntu 8.04.4 LTS through Ubuntu 11.04. Since Ubuntu 10.04 LTS, the boot time has unfortunately increased.
At the request of many Phoronix readers, here are some benchmarks comparing the 64-bit performance of Ubuntu 11.04 versus a recent development build of Ubuntu 11.10. Six different systems were benchmarked for this comparison.
FreeBSD provides a Linux binary compatibility layer that allows 32-bit Linux binaries to be natively executed on this BSD operating system. Linux binary compatibility on FreeBSD allows Linux-only applications to be executed in a near seamless manner on this alternative platform, even for games. New tests have revealed that the modern FreeBSD operating system (via PC-BSD 8.2) can actually outperform Linux when it comes to running OpenGL Linux game binaries.
If you're thinking about trying out the Ubuntu 11.10 Beta release later in the week or are beginning to wonder about what the graphics driver options for Ubuntu 11.10 "Oneiric Ocelot" when released in October, here's a collection of information you'll want to know about the graphics drivers to be found in Ubuntu 11.10.
Fedora 16 Alpha was released earlier this week while the final release is not due until early November. If you have not yet tried out this latest Fedora development release, in this Phoronix article is a brief look through the Red Hat sponsored Linux distribution.
When Apple released Mac OS X 10.7 Lion last week Wednesday, they not only put out their new operating system, but they also released new Mac Mini and MacBook Air hardware. The primary changes for both the Mac Mini and MacBook Air refresh is that both form factors are now shipping with Intel's latest "Sandy Bridge" processors, there is the new Thunderbolt I/O, and of course, they are shipping with Mac OS X 10.7 Lion. This hardware update led me to immediately order the new Mac Mini as the latest piece of Apple hardware at Phoronix. Not because Phoronix is part of the Apple cult (since, after all, Phoronix is the leading Linux hardware site), but an immense curiosity about the Intel Sandy Bridge Mac OS X graphics driver. In particular, to see how Apple's Sandy Bridge driver compares to the Linux and Windows driver. Well, that was the plan at least, prior to the untimely demise of the new Apple hardware.
Last week there was a GNU Hurd status update, which generated a fair amount of attention as it stated there are plans for a Debian GNU/Hurd release in conjunction with Debian "Wheezy" when it's out in late 2012 or early 2013. After being in development for more than 20 years, the Hurd is finally taking some shape. The Debian GNU/Hurd installer for Wheezy is even now working, which I tried out and ended up porting the Phoronix Test Suite to GNU Hurd. In this article is a brief look at Debian GNU/Hurd along with the first-ever benchmarks of Debian GNU/Hurd against Debian GNU/Linux.
Last week we delivered results looking at the power consumption of Ubuntu 11.04 versus Windows 7, which was interesting in its own right, but in this article is a brief look at where Apple's Mac OS X operating system fits in between the power consumption of Ubuntu Linux and Microsoft Windows.
After recently tracking down the major Linux kernel power regression that's present for a vast number of mobile users in Fedora 15, Ubuntu 11.04, and other recent Linux distributions shipping the 2.6.38+ kernel, the sights were turned to see how the power management of Ubuntu 11.04 compares to that of Windows 7 Professional Service Pack 1. In this article are the power consumption results of Ubuntu 11.04 compared directly to Windows 7 Professional 1 on several different systems with distinct notebook and desktop / workstation configurations.
With the extensive Linux power consumption tests that I've been carrying out to solve some nasty Linux kernel power regressions and find other areas for optimization, one of the requests that has come in frequently is to compare the power consumption of the KDE, GNOME, Unity, Xfce, and LXDE desktops. After the article earlier this week to look at how the desktop environments / compositing window managers affect OpenGL performance, I carried out a quick desktop power test. In this article are battery power consumption results for Ubuntu, Kubuntu, Xubuntu, and Lubuntu.
Ending out May, we have an interesting set of tests comparing the performance of Fedora 15 and Ubuntu 11.04. This is looking at the "out of the box" performance of both operating systems on three different systems. Not only is the actual test result looked at, but we also compared the power consumption of the two operating systems.
For those Intel "Sandy Bridge" hardware customers that may be trying out the recent release of Fedora 15, the experience is decent and is in much better shape than the troubling support in Ubuntu 11.04. It is not in tip-top shape as there are some recent optimizations in the Linux kernel and Mesa that haven't landed in Fedora 15 (at least not yet in the form of an update), but it's suitable overall.
To be paired with the release of Phoronix Test Suite 3.2-Grimstad later in the quarter will be the release of OpenBenchmarking.org Live, which is a new incarnation of our PTS Desktop Live Linux distribution. For those not familiar with PTS Desktop Live, our Live DVD/USB Linux environment completely standardizes the software stack so that enthusiasts or organizations wishing to carry out benchmarks can do so to directly compare hardware differences by eliminating all Linux software differences. It is also one easy way to try out benchmarking under Linux since it is just a matter of booting the DVD/USB drive and the testing environment is pre-configured. With OpenBenchmarking.org Live, we are taking PTS Desktop Live one big step further.
Now that we have looked at the Ubuntu power consumption going back as far as Ubuntu 8.04 LTS (and found serious power regressions), the next round of testing is providing the Bootchart results for five different systems also going back as far as Ubuntu 8.04 LTS.
Since Friday there's been a number of Phoronix articles about a very bad power regression in the mainline Linux kernel, which is widespread, Ubuntu 11.04 is one of the affected distributions, and has been deemed a bug of high importance. This yet-to-be-resolved issue is affected Linux 2.6.38 and 2.6.39 kernels and for many desktop and notebook systems is causing a 10~30% increase in power consumption. Nevertheless, this is not the only major outstanding power regression in the mainline tree, there is another dramatic regression now spotted as well that is yet-to-be-fixed.
Ubuntu 11.04 "Natty Narwhal" is set to be released on Thursday and while there are a number of new features to talk about in this latest release, the Phoronix Test Suite software has been busy analyzing the performance of this latest release. There is open-source graphics driver improvements leading to some performance improvements (such as Radeon KMS page-flipping), the famous ~200 line Linux kernel patch to improve responsiveness, and various other enhancements that catch our fancy in Ubuntu 11.04. However, one area where there is a frightening regression in Ubuntu 11.04 is with its power consumption. For mobile devices in many workloads, Ubuntu 11.04 is consuming noticeably more power than in any of the past Ubuntu Linux releases. Sadly, no one seems to have noticed in time since continuous integration testing on Linux seems to happen so haphazardly right now.
For those that follow my personal Twitter feed will know that for the past week I've been closely testing Ubuntu 11.04 and all Ubuntu releases going back to Ubuntu 8.04 on many mobile devices in the office. The overall system performance, power consumption, and boot performance have been the principal targets. However, late this week I discovered a glaring regression: Ubuntu 11.04 is viciously going through power. Compared to Ubuntu 10.10, the power consumption on Ubuntu 11.04 for mobile devices is up about 10% on average but under some workloads, I am seeing the power consumption up by nearly 30%. This is happening on many mobile systems spanning multiple generations of Intel CPUs and with Intel / ATI / NVIDIA graphics. This issue has been tracked down to a frightening kernel regression in the mainline tree that is still not addressed.
Upon the release of the first Mac OS X 10.7 "Lion" Developer Preview, we had delivered early benchmarks of this Apple operating system slated for release this summer. Since then, there has been the release of Mac OS X 10.7 Developer Preview 2 (DP2) so we have carried out an updated set of Mac OS X 10.7 performance benchmarks. This also includes a comparative look at the Mac OS X Lion performance against Ubuntu Linux 10.10.
At the end of 2009 I published benchmarks comparing Ubuntu's 32-bit, 32-bit PAE, and 64-bit Linux kernels. Those tests were carried out to show the performance impact of using 32-bit with PAE (Physical Address Extension) support, which on the plus side allows up to 64GB of system memory to be addressable from 32-bit machines, but is still significantly slower than a 64-bit kernel and user-space. In this article the tests have been carried out on modern hardware and with the latest Ubuntu 11.04 packages to see how the three kernel variants are performing in 2011.
By now you have likely read all about the features announced for Mac OS X 10.7 "Lion" thus far along with seeing plenty of screenshots and videos showing off Launchpad, Mission Control, Versions, the improved mail client, and much more. But how does Apple's next-generation operating system perform? Well, here is a look at the performance of Mac OS X 10.7, including what are likely the first public benchmarks of Mac OS X Lion.
In this article we are looking at how Linux, OpenSolaris, and FreeBSD scale across multiple cores. Benchmarked are CentOS 5.5, Fedora 14, PC-BSD/FreeBSD 8.1, and OpenIndiana b148 as we see how the performance differs when running on one, two, three, four, and six cores, plus when Intel Hyper Threading is enabled.
In recent weeks we have been talking about Intel's Linux advancements as it concerns their latest "Sandy Bridge" generation of processors with integrated graphics (and there are a few more articles on the way), but how is their latest open-source driver stack performing on the older generations of Intel integrated graphics? Previously, the Intel Linux graphics have been the real loser in our multi-OS comparisons, but is this still the case? At least when comparing the Linux and Mac OS X performance on Intel 945 hardware, yes, the Mesa driver falls behind at OpenGL acceleration.
Earlier this week on Phoronix were new benchmarks of Ubuntu Linux vs. Mac OS X using a new Apple Mac Book Pro with an Intel Core i5 CPU and a NVIDIA GeForce GT 330M graphics processor. When looking at the tests results overall it ended up being a competitive race between these two Microsoft Windows competitors. In some areas, like the OpenCL computational performance, Apple's operating system commanded a sizable lead. In other areas, like the OpenGL graphics performance, Ubuntu Linux backed by NVIDIA's official but proprietary driver was in control. Here's an additional set of tests showing the measurable leads of NVIDIA Linux over Mac OS X with Apple's NVIDIA driver.
Back in May, we published benchmarks of Mac OS X 10.6.3 vs. Windows 7 vs. Ubuntu 10.04, along with other times, looking at the performance of Apple's Mac OS X operating system relative to Ubuntu and other Linux distributions. In most of those articles though we used Mac Mini computers, but now with a new Mac Book Pro in our labs with the latest Apple/Intel hardware, along with the most recent versions of each operating system, we have carried out a new set of tests that is also more in-depth than our earlier published benchmarks.
Ubuntu 11.04 Alpha 1 is set to be released today and many of you have been wondering what Canonical's Unity desktop will look like in this forthcoming release codenamed Natty Narwhal. I, for one, have been quite interested based upon the terrible Unity experience in Ubuntu 10.10 Netbook, so I fired up the latest Ubuntu Natty daily LiveCD released this morning. Here are some screenshots of the new Ubuntu Unity desktop as it stands in Natty Alpha 1 along with screenshots of Natty's classic GNOME desktop.
There's been a number of individuals and organizations asking us about benchmarks of Red Hat Enterprise Linux 6.0, which was released earlier this month and we had benchmarked beta versions of RHEL6 in past months. For those interested in benchmarks of Red Hat's flagship Linux operating system, here are some of our initial benchmarks comparing the official release of Red Hat Enterprise Linux 6.0 to Red Hat Enterprise Linux 5.5, openSUSE, Ubuntu, and Debian.
Recently we published benchmarks of Debian with the Etch, Lenny, and Squeeze releases. This is as far back as we could benchmark before hitting the 2.4 Linux kernel and running into hardware compatibility issues and other problems, considering Debian GNU/Linux doesn't seen an official release nearly as often as Ubuntu, Fedora, or most other distributions. We have now carried out a similar process, but on the Fedora side, and here we were able to go all the way back to the 2004 release of Fedora Core 3. Here are benchmarks of Fedora Core 3 with every release up through the recent release of Fedora 14.
Earlier today we put out benchmarks of ZFS on Linux via a native kernel module that will be made publicly available to bring this Sun/Oracle file-system over to more Linux users. Now though as a bonus we happen to have new benchmarks of the latest OpenSolaris-based distributions, including OpenSolaris, OpenIndiana, and Augustiner-Schweinshaxe, compared to PC-BSD, Fedora, and Ubuntu.
With Debian 6.0 "Squeeze" set to be released in the coming months, we have decided to run a set of benchmarks looking at the performance of Debian 6.0 across different sub-systems relative to the performance of Debian 5.0 "Lenny" and Debian 4.0 "Etch" to see how this new release may stack up.
