July 16, 2012 -- With Ubuntu 12.10 coming up in just a few months, here are our first virtualization benchmarks from the forthcoming "Quantal Quetzal" operating system. Compared in this article is the raw/bare-metal performance to Linux KVM and Xen virtualization from the latest Linux 3.5 kernel.
June 27, 2012 -- It has been a while since last benchmarking the ZFS file-system under Linux, but here's some benchmarks of the well-known Solaris file-system on Ubuntu 12.04 LTS and compared to EXT4 and Btrfs when using both a hard drive and solid-state drive.
June 13, 2012 -- Here are some OpenCL benchmarks from the Intel Ivy Bridge CPU. Being compared though is AMD's APP SDK, which does support running OpenCL on x86 CPUs, to Intel's CPU-based OpenCL SDK for Linux. To some surprise, AMD's Accelerated Parallel Processing SDK when using the Ivy Bridge CPU is actually faster than the Intel OpenCL SDK on the same hardware.
June 11, 2012 -- Issued as a stable release update to Ubuntu 12.04 LTS last week was Unity 5.12. Aside from offering some minor usability enhancements and various fixes, Unity 5.12 should fix some of the OpenGL performance problems that many users have experienced -- and multiple Phoronix articles have noted the OpenGL performance slowdown -- so here's some tests seeing how Unity 5.12 now affects the OpenGL gaming performance.
June 05, 2012 -- In this article is a look at the impact that compiler tuning has for the latest-generation Intel Ivy Bridge processors. Being tested is the GNU Compiler Collection (GCC) while passing various architecture flags to look at the impact they have on the results.
May 31, 2012 -- As the latest Intel Ivy Bridge numbers to push out, here is a look at the Linux virtualization performance with the Core i7 3770K processor when comparing its raw/bare-metal performance to Linux KVM (Kernel-based Virtual Machine) virtualization and Oracle VM VirtualBox under Ubuntu 12.04 LTS.
May 30, 2012 -- From an Intel Core i7 3770K "Ivy Bridge" system here is an 11-way compiler comparison to look at the performance of these popular code compilers on the latest-generation Intel hardware. Among the compilers being compared on Intel's Ivy Bridge platform are multiple releases of GCC, LLVM/Clang, DragonEgg, PathScale EKOPath, and Open64.
May 29, 2012 -- Following the Linux 3.4 kernel benchmarks from last week, available now are the results from a three-way file-system comparison using the Linux 3.4 kernel as well as the Linux 3.2 and 3.3 kernels for reference. The three file-systems being pitted against each other are Btrfs, EXT4, and XFS.
May 28, 2012 -- As the latest Intel Ivy Bridge Linux graphics benchmarks to publish, here is a comparison of some of the different desktop environment options of Ubuntu 12.04 LTS when using the Intel Linux graphics driver on the Core i7 3770K with its HD 4000 graphics. The desktop environments being compared include Unity, Unity 2D, KDE, and Xfce. The default Ubuntu Unity desktop with Compiz continues to have problems for the open-source friendly company's drivers.
May 25, 2012 -- Here's a look at the performance of the Linux 3.4 kernel, which was recently released, compared to all major kernel releases going back to Linux 2.6.39. Multiple kernel sub-systems are being compared in this round of Intel Linux benchmarking.
