Testing Out Ubuntu's Unity Desktop

As we reported this morning, via a blog post and keynote to kick-off the start of the Ubuntu Developer Summit this week for engaging in Ubuntu 10.10 development activities, Mark Shuttleworth announced Ubuntu Light and Ubuntu Unity. Ubuntu Light is a new spin of Ubuntu that is being offered up to OEMs that are looking to offer Ubuntu Linux as part of a dual-boot installation on their PCs. Unity is the new Ubuntu desktop interface that is used by Ubuntu Light.

Towards A Real Business Model For Open-Source Software

Last week in a FreeBSD status report we talked about the Chromium web-browser support on FreeBSD improving through a new subscription program whereby most of the FreeBSD patches are being kept closed-source for some length of time before being committed back upstream as open-source and reaching the hands of the non-subscribers. This caused some to question the work, but the developer behind this FreeBSD-Chromium subscription program, Sprewell, has written an editorial that we are now publishing. This details his beliefs concerning the future of open-source software business models.

Benchmarking LLVM & Clang Against GCC 4.5

With the recent release of GCC 4.5 and the forthcoming release of LLVM 2.7 that is expected in the coming days, we have decided to see how the performance of GCC compares to that of LLVM. For this testing we have results from GCC 4.3/4.4/4.5 compared to LLVM with its GCC front-end (LLVM-GCC) and against Clang, which is the native C/C++ compiler front-end for the Low-Level Virtual Machine.

Benchmarks Of GCC 4.5.0 Compiler Performance

Last week GCC 4.5.0 entered the world with improvements to the experimental C++0x support, Graphite-powered automatic parallelization support, compatibility with new ARM processors, Intel Atom and AMD Orochi optimizations, link-time optimization, and GCC plug-in support. Over the weekend we decided to benchmark this major update to the GNU Compiler Collection to see how its performance compares to that of GCC 4.3 and 4.4.

Btrfs System Rollbacks In Fedora 13

One of the benefits of Btrfs besides offering competitive performance against other Linux file-systems and SSD optimizations is its support for sub-volumes and writable snapshots. While Btrfs is still in development and is not yet used as a default file-system by any Linux distribution, Red Hat has been looking to capitalize upon the capabilities of Btrfs by introducing support for system rollbacks into Fedora. The Btrfs-based system rollback support has been a feature for Fedora 13 so with the release of the Fedora 13 Beta earlier this week we decided to further investigate this feature.

File-System Benchmarks With The Linux 2.6.34 Kernel

File-system benchmarks have become quite common to Phoronix in the age of EXT4 and Btrfs with these new file-systems driving much of the interest and as we have also been finding the Linux file-system performance to change between kernel releases (and in some cases, the performance has changed a great deal). Most recently we delivered benchmarks of EXT4 vs. Btrfs vs. Reiser4, but now a month later we are back with more Linux file-system benchmarks as we look to see if the disk performance has changed with the Linux 2.6.34 kernel.

Lexmark's Linux Secret

Most of the time at Phoronix we focus on looking at the Linux graphics performance of the software drivers and hardware, since traditionally that has been one of the most troubling areas of Linux hardware support. Tides though have turned as AMD continues to back their own open-source strategy with providing documentation and pushing out code that enables open-source hardware support from 3D acceleration to power management, while Intel continues to back their fully open-source model too. Another area of hardware support that has caused much grief for users has been with printer support. Printers are not nearly as complex as a modern-day graphics processor, but the different vendors have not been quick to offer up any Linux support -- and binary-only drivers frequently back the ones that do. There is one printer manufacturer though that as of last year has begun supporting Linux from top to bottom with their entire line-up of printers. Not only are they providing CUPS drivers, but also they are even printing Tux in the corner of every box they ship right besides the Windows and Apple logos. Do you know who we are talking about? Probably not, but it's Lexmark. After months of wrangling within the company, Lexmark has stepped up to become a Linux and open-source friendly company. We are seeing how far this Linux support extends as we try out the Lexmark Pro905 Platinum multi-function printer.

Coming Soon: X Server 1.8

According to the release plans, the release of X Server 1.8 should take place, and while in reality it will likely not be released today, its release is coming soon. When this release does arrive, it will add a new set of features to the X.Org stack and a number of other minor improvements and bug-fixes.

Bam! Phoromatic 1.0 Unleashed & Ubuntu Joins The Party

Phoromatic, our remote test management system that makes it incredibly simple to deploy the Phoronix Test Suite across an array of systems within an organization or around the world, has been in development for more than a year. We publicly announced this unique enterprise solution when developing Phoronix Test Suite 2.0 and it publicly went into beta with Phoronix Test Suite 2.2 where it became possible to easily build a benchmarking test farm using our Phoronix software. Before ending out the year we launched Phoromatic Tracker with an initial reference implementation to monitor the Linux kernel performance on a daily basis and in a fully automated manner. Phoromatic has been a huge success, but today we are announcing that Phoromatic has reached a 1.0 status and additionally we are providing the Ubuntu Linux community with a new performance tracker in collaboration with Canonical.

Testing The Different Ubuntu 10.04 Kernels

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.
