  • Supports over 220 test profiles and over 60 test suites;
  • Uses an XML-based testing architecture. Tests include MEncoder, FFmpeg and lm sensors along with OpenGL games such as Doom 3, Nexuiz, and Enemy Territory: Quake Wars, and many others;[7]
  • Contains a feature called PTS Global where users are able to upload their test results and system information for sharing. Then through executing a single command, other users can compare their test results to a selected system in an easy-comparison mode;[8]
  • Allow report benchmark results to the Phoronix Global online database;
  • Allow compare results side-by-side;
  • Is extensible and new tests can be added easily;
  • Can do anonymous usage reporting;
  • Can do automated Git bisecting on a performance basis to find performance regressions. It features statistical significance verification.



Phoromatic is an web-based remote test management system for the Phoronix Test Suite. It does automatic scheduling of tests. It is aimed at the enterprise. It can manage multiple test nodes simultaneously within a test farm or distributed environment.

Phoromatic Tracker

Phoromatic Tracker is an extension of Phoromatic that provides a public interface into test farms.[9] Currently their reference implementations autonomously monitor the performance of the Linux kernel on a daily basis,[10] Fedora Rawhide[11] and Ubuntu.[12]

PTS Desktop Live

PTS Desktop Live was a stripped down x86-64 Linux distribution, which included Phoronix Test Suite 2.4. It was designed for testing/benchmarking computers from a LiveDVD / LiveUSB environment.[13]


Phodevi (Phoronix Device Interface) is a library that provides a clean, stable, platform-independent API for accessing software and hardware information.


Phoronix Certification & Qualification Suite (PCQS) is a reference specification for the Phoronix Test Suite.

Phoronix is a technology website that offers insights regarding the development of the Linux kernel, product reviews, interviews, and news regarding free and open-source software by monitoring the Linux kernel mailing list or interviews.

Phoronix was started in June 2004 by Michael Larabel, who currently serves as the owner and editor-in-chief.


Founded on 5 June 2004,[14] Phoronix started as a website with a handful of hardware reviews and guides,[15][16] moving to articles covering operating systems based on Linux and open source software around the start of 2005, such as Ubuntu, Fedora, SUSE[17] and Mozilla (Firefox/Thunderbird).[18] Phoronix heavily focuses on benchmarking hardware running Linux, with a heavy slant towards graphics articles that monitor and compare free and open-source graphics device drivers and Mesa 3D with AMD's and Nvidia's proprietary graphics device drivers. In June 2006 the website added forums in addition to news content.[19] On 20 April 2007, Phoronix redesigned its website,[20] and began Solaris hardware reviews and news in addition to Linux content.[21]

Phoronix benchmarks have been cited by a number of other technical publications such as CNET News[22][23] and Slashdot.[24]

OpenBenchmarking is a web-based service created to work with the Phoronix Test Suite. It is a collaborative platform that allows users to share their hardware and software benchmarks through an organized online interface.[25]

On 5 June 2008, Phoronix Test Suite 1.0 was released under the codename Trondheim.[26] This 1.0 release was made up of 57 test profiles and 23 test suites.[27]

On 3 September 2008, Phoronix Test Suite 1.2 was released with support for the OpenSolaris operating system[28] and a module framework accompanied by tests focusing upon new areas[29] and many new test profiles.

Phoronix Test Suite 1.8 includes a graphical user interface (GUI) using GTK+ written using the PHP-GTK bindings.

3.4 includes MATISK benchmarking module and initial support for the GNU Hurd.


Phoronix uses Phoronix Test Suite to compare performance of different operating systems Linux distributions, OpenSolaris, and FreeBSD. Critics of Phoronix Test Suite argue that some of the third-party tests are unfair towards some platforms.

The compiler used in building the source based tests have a large impact on the results. Depending on the reader's point of view this is seen as a detriment to the value of the results. However other readers may see that as a realistic expectation of performance for that particular system with that operating system. PTS 3.8 reports compiler options and compiler differences between test runs.
