Ubuntu 11.04: i686 vs. i686 PAE vs. x86_64

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.

Early Benchmarks Of Mac OS X 10.7 Lion

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.

Multi-Core, Multi-OS Scaling Performance

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.

Mac OS X Intel Graphics Still Outperform Linux

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.

Linux Can Deliver A Faster Gaming Experience Than Mac OS X

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.

Ubuntu 10.10 vs. Mac OS X 10.6.5: A Competitive Race

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.

The Desktop Faces Of Ubuntu 11.04 Alpha 1

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.

Red Hat Enterprise Linux 6.0 Benchmarks

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.

The Performance Of Fedora Core 3 Through Fedora 14

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.

New Benchmarks Of OpenSolaris, BSD & Linux

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.
