When running my initial Linux 3.16 file-system tests on an SSD I had to skip over Btrfs due to initial problems with the experimental kernel code. Fortunately, Btrfs has been fixed-up in Linux 3.16 and can now serve for some benchmarking.

Phoronix benchmarks have shown that when using the Linux 3.16 kernel, the Nouveau performance is faster when taking advantage of the experimental re-clocking. Additionally, the Radeon graphics performance is faster on Linux 3.16 for newer graphics cards thanks to other optimizations. For Intel Haswell Linux users are there any performance improvements in store for Linux 3.16? Here's some tests.

There's been numerous requests lately for more disk I/O scheduler benchmarks on Phoronix of the Linux kernel and its various scheduler options. Given that there's routinely just speculation and miscommunication by individuals over the best scheduler for HDDs/SSDs, here's some fresh benchmarks for reference using the Linux 3.16 kernel.

While yesterday's Linux testing at Phoronix revealed Intel Bay Trail graphics are slower than Windows when running in comparison the updated open-source Intel Linux graphics stack, at least the Bay Trail performance for Intel's N2820 NUC has improved in the past few months under Linux.

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.
