The Top Phoronix Stories Of 2010

With 2010 now coming to an end, what were the most popular Phoronix stories this year? For those curious about the most viewed articles and news posts on Phoronix in 2010, here's a list. Exclusive information on Valve's forthcoming Linux Steam client, photographs from my adventure to the Chernobyl Nuclear Disaster Site, and multi-OS benchmarks had dominated 2010.

Benchmarks Of The Btrfs Space Cache Option

In early November we delivered benchmarks of EXT4 vs. Btrfs on an early Linux 2.6.37 kernel as our latest round of tests comparing these two leading Linux file-systems. There were some changes in the Linux disk performance with these file-systems using the latest Linux kernel code, but overall it was not too interesting. However, as the Linux 2.6.37 kernel does introduce a new mount option for Btrfs, the space_cache option, we decided to explore its performance in today's article.

Linux Gaming: Native vs. Wine vs. Windows 7 Performance

Linux gaming has a bright future ahead with the forthcoming Unigine games, successful indie campaigns, and many other Linux-native game titles being just out on the horizon. Right now though if you are a dedicated PC gamer looking to satisfy your entertainment appetite under Linux, more than likely you find yourself using the Wine program so that you can run many Windows programs under Linux. What is the performance impact though of using this method? In this article, we have a couple benchmarks comparing the performance of Wine, native Linux game binaries, and the native Microsoft Windows 7 Professional performance.

Linux KVM vs. VirtualBox 4.0 Virtualization Benchmarks

Oracle's been vigorously working on their VM VirtualBox 4.0 software and in just the past week they have delivered two public betas that bring a number of new features. Among the changes there is support for Intel HD audio / ICH9 to guest VMs, the concept of extension packs, user-interface improvements, support for limiting a virtual machine's CPU time and I/O bandwidth, 3D acceleration fixes for guests, and a great number of bug-fixes. How though is this updated Oracle/Sun virtualization platform comparing to the older VirtualBox 3.2 release and that of the upstream Linux KVM (the Kernel-based Virtual Machine) that most Linux distributions rely upon? Here are a number of benchmarks that seek to answer this very question.

Speeding Up The Linux Kernel With Transparent Hugepage Support

Last month we reported on the 200 line Linux kernel patch that does wonders for improving the desktop responsiveness of the system. There was certainly much interest (over 100,000 views to both of our YouTube videos demonstrating the change) but this patch really didn't speed up the system per se but rather improved the desktop interactivity and reduced latency by creating task-groups per TTY so that the processes had more equal access to the CPU. There is though an entirely different patch-set now beginning to generate interest among early adopters that does improve the kernel performance itself in compute and memory intensive applications and it's the Transparent Hugepage Support patch-set. Here are our initial tests of the latest kernel patches that will hopefully be finding their way into the mainline Linux kernel soon.

Ubuntu: Faster, But More Power Hungry Than Mac OS X?

Earlier this week I noted there's new Apple hardware in our labs being used to tighten up our Mac OS X support within the Phoronix Test Suite, OpenBenchmarking.org, Phoromatic, etc. However, in the middle of working on Iveland, I have been carrying out a few Mac OS X benchmarks comparing its performance under the 2010 Apple Mac Book Pro to other operating systems. With the Core i5 notebook being much faster than the past Apple Mac Minis used in comparisons like looking at their enhanced OpenGL stack and benchmarking Mac OS X against Linux and Windows 7, the results are more interesting and there's also a greater variety of testing possibilities now with the recent Phoronix Test Suite advancements. Next week there are some very interesting Apple-related benchmarks to be published, but before the weekend here are a few tests from this Apple Mac Book Pro looking at its power consumption under Mac OS X 10.6.5 and Ubuntu 10.10.

Adobe's Flash Video Acceleration For Linux Works Well

There is the first beta release of the Adobe 10.2 Flash Player now available for Microsoft Windows, Apple Mac OS X, and Linux platforms that brings a variety of improvements since the Flash Player 10.1 release from earlier this year. For Linux users this Adobe Flash update is quite important since it finally delivers GPU-based video acceleration support via their new Stage Video technology that is now supported on all platforms. Adobe's Stage Video offloads the entire video process to the GPU and in this article are some initial tests illustrating the benefits of this Flash update for Linux users.

GCC & LLVM Clang Performance On The Intel Atom

A few weeks ago there were benchmarks of GCC, LLVM-GCC, DragonEgg, and Clang. In this compiler performance comparison the releases of GCC 4.2, 4.3, 4.4, 4.5, and a 4.6 development snapshot were benchmarked. On the LLVM side there was LLVM-GCC 4.2, DragonEgg with GCC 4.5 and LLVM 2.8, and then Clang with LLVM 2.8. This combination of eight open-source compilers were tested on three distinct Intel and AMD systems (even a 12-thread Core i7 Gulftown), but all of which were 64-bit capable and contained relatively high-end processors from their respective series. To complement this earlier article, available now are some new GCC/LLVM benchmarks but this time an older Intel Atom CPU was used to look at the 32-bit compiler performance on a slower, low-power netbook.

It's Becoming Very Easy To Run Wayland

When Wayland started out in 2008 it was very difficult to build and run this lightweight, next-generation display server. Wayland leverages the very latest Linux graphics technologies and at that time all of Wayland's dependencies had to be patched or built from branched sources and Wayland even had its own EGL implementation at the time (Eagle) rather than Mesa and overall it was just a high barrier to entry. Wayland at that time also worked with only the open-source Intel driver, while now it can work with most any KMS / GEM / Mesa driver. It was not until recently that it became possible to build Wayland from mainline components beginning to ship in new Linux distributions, thereby making it much easier to experiment with the open-source display server. Now it's to a point where you can just run a simple script and be up and running with a Wayland Display Server in just minutes.

Karsk: Make Finding Software/Driver Optimizations Easier

When publishing ATI Gallium3D benchmarks this week that compared the performance of the Radeon HD 4870 and Radeon HD 5770 graphics cards with this next-generation driver architecture to the classic open-source Mesa driver and AMD's high-performance proprietary Catalyst driver, the results were what one would mostly expect. The Gallium3D driver was faster than the classic Mesa driver in most tests, but both drivers seriously lagged behind the proprietary driver. Even on older generation ATI Radeon graphics cards this is the case. This though has led many to effectively ask, "what's keeping the open-source drivers from performing like the proprietary driver?" It all comes down to low-level optimizations as is discussed in this Phoronix Forums thread. There are very large development teams for the different Catalyst driver components within AMD and much of this work is shared across all platforms, but on the open-source Linux side there's very few paid full-time developers and just a number of part-time, community developers to cover the entire driver stack.
