The most common Linux file-systems we talk about at Phoronix are of course Btrfs and EXT4 while the ZFS file-system, which is available on Linux as a FUSE (user-space) module or via a recent kernel module port, gets mentioned a fair amount too. When it comes to the FreeBSD and PC-BSD operating systems, ZFS is looked upon as the superior, next-generation option that is available to BSD users. However, with the DragonFlyBSD operating system there is another option: HAMMER. In this article we are seeing how the performance of this original creation within the DragonFlyBSD project competes with ZFS, UFS, EXT3, EXT4, and Btrfs.

In December we published our first set of Amazon EC2 benchmarks for their Elastic Compute Cloud using Ubuntu EC2 and the different instances that were compatible. Now though we are in the process of carrying out a new set of benchmarks from Amazon's cloud that not only contains more tests, but using the official Amazon Linux AMI we tested nearly every instance type. Except what is missing are the results for the "micro" (the t1.micro API name) instance. Why? It is simply too slow and irregular.

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.

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 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.

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.

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.

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.

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.

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.
