We have published articles containing EXT4 benchmarks many times now going back to our original real world benchmarks of EXT4 to when Ubuntu 9.04 received EXT4 support and when we ran a variety of file-system benchmarks on an Intel X25-E SSD. We had also thrown in EXT4 numbers when benchmarking Btrfs (and again with Btrfs 0.19) along with NILFS2 benchmarks. Each time has been with a different kernel and the performance of the different Linux file-systems continue to change as each file-system matures and picks up different features. Though with the Linux 2.6.32 kernel the EXT4 performance had changed a great deal due to a change that provides better data integrity on writes but at a significant performance cost. To see how this changes the Linux file-system landscape, atop the latest Linux kernel we have a fresh set of benchmarks for EXT3, EXT4, XFS, ReiserFS, and Btrfs.

Only two weeks have passed since the launch of Phoronix Test Suite 2.2, but it is already time to push out the first alpha release for Phoronix Test Suite 2.4! Phoronix Test Suite 2.4 (codenamed "Lenvik") Alpha 1 is what is running on our kernel test farm that launched yesterday and there is already a great deal of changes to be found in this release. In fact, the patch already between 2.2 Bardu and 2.4 Lenvik Alpha 1 is nearly 24,000 lines of code! There is some code reorganization, but a lot of new code has been introduced. Here is some of what can be found already in this development release.

This year with the Phoronix Test Suite we have delivered four major updates to this leading, widely adopted, multi-platform testing software that has brought dozens of new test profiles and literally hundreds of significant changes. These changes ranged from features to autonomously track performance regressions within any code-base, the ability to not only compare frame-rates within OpenGL tests but image quality comparisons too, support for mobile platforms, and so much other major work to further drive automated testing and benchmarking not only on Linux but OpenSolaris, *BSD, and Mac OS X too. In 2009 we also launched PTS Desktop Live, our own operating system for carrying out standardized benchmarks in an easy-to-use and repeatable manner from a live Linux environment, and also Phoromatic, which is designed for the enterprise world and allows the Phoronix Test Suite to be easily deployed across many systems and then managed from a central interface. The year is not over yet, nor is our work on ensuring that the Phoronix Test Suite is the most powerful and robust testing/benchmarking platform. With that said, as of this morning our Phoronix kernel test farm is now alive!

With the Linux 2.6.32 kernel being released in a few days, we found it time to benchmark this newest kernel release that brings new drivers, kernel mode-setting improvements, virtualization enhancements, and more.

Yesterday marked the release of Phoronix Test Suite 2.2 and it was the best version yet with the addition of many new exciting and useful features. While this release was gratifying, there are much greater plans for the Phoronix Test Suite going into the next decade. It has already been shared that Windows support is coming, but there are other huge features coming too as soon as Q1'2010. Up to this point, most of the tests and the design of pts-core (the Phoronix Test Suite engine) have been focused on quantitative benchmarks with many of the tests spitting out a frame-rate, time, or some other measurement. However, now being supported in the Phoronix Test Suite is the ability to produce abstract results, such as screenshots used for image quality comparisons. The Phoronix Test Suite can now track the image quality of various test profiles (such as OpenGL games) across hardware configurations, drivers, and more. All of this is still leveraged upon the existing Phoronix Test Suite framework and our design philosophies so that even image quality comparisons can be carried out autonomously, the ability to compare many results side-by-side, support for carrying out these tests remotely via Phoromatic, and the ability to share your abstract results with others via Phoronix Global. Now not only can you be sure you are satisfied with the quantitative frame-rate of the hardware you have -- or are about to purchase -- but you have a plethora of options for looking at the qualitative performance too.

Continuing in the tradition of providing feature-rich, quarterly updates to the Phoronix Test Suite, Phoronix Media has announced the immediate availability of Phoronix Test Suite 2.2 (codenamed "Bardu"). Phoronix Test Suite 2.2 continues to expand the capabilities and feature set for this open-source testing framework with the introduction of many new features, a new graphical user-interface, numerous new test profiles and suites, and a public beta of the Phoromatic remote test management system.

There's the Phoronix Test Suite, Phoronix Global, and PTS Desktop Live as our family of free software products to provide extensive benchmarking and automated testing capabilities atop Linux, OpenSolaris, BSD, and Mac OS X operating systems. The Phoronix Test Suite has more than 120 test profiles and 50 test suites with new suites and tests continuing to come in through its extensible architecture, but for organizations with multiple test systems or entire testing farm(s) devoted to performance monitoring and regression tracking, they have had to strap the Phoronix Test Suite atop their own management systems or hack away at simple scripts to deploy our testing software across an array of systems. Today though we are announcing the public beta launch of Phoromatic. Phoromatic is a remote test management system that allows controlling any number of PTS-powered systems through a single web-based interface, which also allows all of the test results to be viewed from a central source. This article provides a first-look and guide for some of the possibilities of Phoromatic from those looking to build a benchmarking test farm or for individuals simply wanting to benchmark computers across the world. We also share in this article what may be coming next to our Linux-focused benchmarking empire.

After a three month development period following the release of Phoronix Test Suite 2.0, the first beta release of Phoronix Test Suite 2.2 "Bardu" is now available for all of your testing needs on Linux, Mac OS X, OpenSolaris, and BSD platforms. Phoronix Test Suite 2.2 Beta 1 carries more than 200 changes since the release of 2.0 Sandtorg with many new prominent features being introduced, new test profiles added, and greater usability enhancements. In this article, we will go over some of the key improvements to be found in Phoronix Test Suite 2.2.

Last weekend a few Phoronix benchmarks were underway of the Linux 2.6.32-rc5 kernel when a very significant performance regression was spotted. This regression caused the PostgreSQL server to run at about 18% of the performance found in earlier kernel releases. Long story short, in tracking down this performance regression we have finally devised a way to autonomously locate performance regressions within the Linux kernel and potentially any Git-based project for that matter. Here are a few details.

Earlier this month at the Red Hat Summit where Red Hat Enterprise Linux 5.4 was released with support for the Kernel-based Virtual Machine. At this Red Hat event, virtualization -- particularly KVM -- and cloud computing were the most talked about topics. But how is KVM performing these days? With new virtualization refinements going into almost every new Linux kernel release, we have published a new set of KVM benchmarks using the Linux 2.6.31 kernel, to provide updated numbers against our KVM benchmarks from last year and our Core i7 virtualization numbers. This time around, we are also using a Phenom II processor for testing out the AMD-V technology.
