With the upstream Linux kernel nearly compatible with LLVM's Clang compiler as an alternative to using GCC, I benchmarked the latest "LLVMLinux" code that's the Linux kernel compiled under Clang with some out-of-tree patches to see how its performance compares to a conventionally built kernel with GCC 4.8.

With it looking like LLVM Clang 3.5 might finally have OpenMP support, I tested out Intel's latest out-of-tree LLVM/Clang OpenMP code to see how the performance compares to GCC for this multi-processing API. Overall, the Clang results increase the level of competition against GCC.

With the release of Intel's PowerTOP 2.6 a few days ago I have done some benchmarking using an ASUS Zenbook Prime ultrabook to see the impact of the power consumption while running on battery for a clean, stock install of Ubuntu 14.04 LTS 64-bit and then did the same tests again after having PowerTOP 2.6 optimize the system so it's in a good power standing. Beyond testing the stock Linux 3.13 kernel, then I carried out the same tests again when using the Linux 3.15 kernel in its very latest development state.

There's been many requests to run some new OpenGL and 2D performance benchmarks under different Linux desktop environments. With the imminent release of Linux Mint 17 and it shipping the latest version of the increasingly-popular Cinnamon Desktop Environment, here's a six-way desktop performance comparison using Intel graphics on Linux Mint 17.

For this weekend's Linux benchmarks we are looking at the performance of the Intel P-State and ACPI cpufreq drivers and comparing their scaling governor options when testing from an Intel Core i7 Extreme Edition system running with the Linux 3.15 development kernel.

Recently I posted new benchmarks showing LLVM's Clang compiler performing well against GCC from AMD's x86-based Athlon APUs with the performance of the resulting binaries being quite fast but not without some blemishes for both of these open-source compilers. In seeing how the compiler race is doing in the ARM space with many ARM vendors taking interest in LLVM/Clang, here's some fresh benchmarks of both compilers on NVIDIA's Tegra K1 SoC found by the Jetson TK1 development board.

After earlier in the week delivering solid-state drive file-system benchmarks in comparing the Linux 3.15 FS performance to Linux 3.14 stable, now it's time to do a Linux 3.14 vs. 3.14 file-system performance comparison with a traditional hard drive. The file-systems being benchmarked here are EXT4, XFS, and Btrfs.

Now that kernel development activity is settling down for the Linux 3.15 kernel, here are some benchmarks of the EXT4, XFS, F2FS, and Btrfs file-systems compared to the stable Linux 3.14 kernel performance.

A common benchmark request at Phoronix lately has been to compare the Xen PV (para-virtualization) performance to Xen HVM (Hardware-assisted virtualization). Well, now that Ubuntu 14.04 LTS has been released, here's some benchmarks from within Amazon's EC2 compute cloud when comparing Ubuntu 14.04 Server PV and HVM instances.
