The release of Ubuntu 10.04 LTS "Lucid Lynx" is quickly approaching next month and it will arrive with a whole set of new features and improvements including a faster boot process, a long-awaited new theme, the Nouveau driver to replace the crippled xf86-video-nv driver, the unveiling of the Ubuntu One Music Store, integration of Plymouth, Ubuntu ARM advancements, and many other advancements for this Linux distribution. While it may not be as exciting as looking at these new end-user features, in this article we are testing out the available kernels for Ubuntu 10.04. Besides the standard Linux 2.6.32 kernel used in the Lucid release, there is also a specialized server kernel as well as a new -preempt kernel is now available. We are looking at how these different kernels perform and how they compare to the mainline Linux kernels with the 2.6.32, 2.6.33, and 2.6.34-rc1 releases.

Fedora 13 Alpha was released yesterday with a plethora of new features and updated packages for this Red Hat Linux distribution. Aside from the features like Btrfs system rollback support and PolicyKit One support for Qt/KDE applications to excite end-users, each Fedora release always pulls in the very latest Linux graphics code. Fedora was the first distribution shipping with the Nouveau driver, then its KMS driver, and now with Fedora 13 it's the first OS deploying Nouveau's Gallium3D driver (there's benchmarks behind that link). Fedora 13 is also carrying the latest packages for the unreleased X Server 1.8, DisplayPort monitor support for more graphics cards, the latest ATI driver code from the xf86-video-ati DDX to the in-development DRM, and then there is the very latest Intel work too. To get an idea for the direction that the Intel 3D support is heading in this release, we have carried out a few quick OpenGL benchmarks.

Xfce, LXDE, and other desktop environments are often referenced as being lighter-eight Linux desktop environments than KDE and GNOME, but what are the measurable performance differences between them? Curious how much of a quantitative impact the GNOME, KDE, Xfce, and LXDE desktops have on netbook systems, we carried out a small set of tests to look at the differences in memory usage, battery power consumption, and thermal performance.

There is no shortage of EXT4 benchmarks from comparing this evolutionary file-system's performance on netbooks to how it battles the Btrfs file-system to its performance recession. We have even benchmarked it on USB flash drives and on high-end SSDs. We have also delivered numerous Btrfs benchmarks. In this article though we are finally delivering something that has long been requested and that is Reiser4 file-system benchmarks running directly against EXT4 and Btrfs. We have also thrown in the original ReiserFS file-system for comparison too.

At Phoronix we have been benchmarking the Linux kernel on a daily basis using Phoromatic Tracker, a sub-component of Phoromatic and the Phoronix Test Suite. We launched our first system in the Linux kernel testing farm just prior to the Linux 2.6.33 kernel development cycle and found a number of notable regressions during the past three months. Now with the Linux 2.6.34 kernel development cycle getting into swing, we have added an additional two systems to our daily kernel benchmarking farm. One of the systems is an Atom Z520 system but what makes it more interesting is that the system is using a Btrfs file-system and then the second new system added to the kernel tracker is a 64-bit setup. However, to provide a historical look at the Linux kernel performance, we have ran some fresh benchmarks going back to the Linux 2.6.24 kernel and ending with the recently released Linux 2.6.33 kernel.

In December we wrote that Ubuntu 10.04 already shortened the boot time, which has been a great focus amongst Canonical and Ubuntu developers as they strive for a ten second boot. A lot has changed since that article was published last year, including the introduction of Plymouth and many kernel mode-setting improvements along with the introduction of Nouveau for NVIDIA KMS support. We've ran a new boot performance comparison on two laptops and a netbook as we see how the boot times are looking with Ubuntu 10.04 LTS when compared to Ubuntu 9.10. We have also looked at how the power consumption has changed in the Lucid Lynx for these mobile devices.

This weekend at the Southern California Linux Expo in Los Angeles, Matthew Tippett and I presented a talk entitled Five Stages of Benchmark Loss: PTS and You. In this hour-long talk, we covered Linux benchmarking, what has been learned over the years of benchmarking at Phoronix, the Phoronix Test Suite, and the five stages that users and developers generally go through when they lose out on benchmarking results. For those that were unable to attend this event, here are the slides and recordings.

Last month we published benchmarks of EXT4 comparing this file-system's performance when it was first marked stable in the mainline kernel and then where it is at now in the Linux kernel while testing every major release in between. This article was followed up by a Btrfs versus EXT4 comparison using the Linux 2.6.33 kernel to see how the two most talked about Linux file-systems are battling it out with the latest kernel. After those Linux file-system benchmarks were published, we received a request from Canonical to look at the EXT3 performance too. With that said, we have done just that and have published EXT3, EXT4, and Btrfs benchmarks from Ubuntu 9.10 and a Ubuntu 10.04 development snapshot from an Intel Atom netbook.

Phoronix Media has announced the immediate release of Phoronix Test Suite 2.4 (codenamed "Lenvik"), as the latest update to their open-source testing framework that delivers immediate and measurable advantages to its customers. The Phoronix Test Suite 2.4 software is compatible with a greater number of operating systems, introduces support for mobile platforms, offers a new range of test profiles, and other features to further solidify its premiere position within the computer benchmarking industry.

Earlier this week we published extensive benchmarks of EXT4 that looked at the performance of this Linux file-system under every major kernel release since it was declared stable in the Linux 2.6.28 release. EXT4 has encountered many significant performance losses over time as its developers batten up the data security, but there have been some improvements too. At the same time though the developers working on the still-experimental Btrfs file-system continue to move along and push forward changes with each kernel cycle. Just last month we delivered Btrfs comparative benchmarks using the Linux 2.6.32 kernel, but already out of our own personal interest and requests from readers, we have new tests atop the latest Linux 2.6.33 kernel.
