  • Btrfs RAID5/RAID6 Support Finally Get Fixed (Phoronix)
    Over the summer we wrote about Btrfs RAID 5/6 code was found to be unsafe and likely would need a rewrite. Months later, patches have finally emerged to fix the faulty Btrfs RAID 5/6 code...
  • Benchmarks Of LLVM Clang 6.0 Through Clang 10.0 Compilers (Phoronix)
    At the end of 2019 I ran some GCC 5 through GCC 10 compiler benchmarks while here are the similar tests conducted on the LLVM side for seeing how the Clang C/C++ compiler performance has evolved over the past few years...
  • The Kubuntu Focus KDE Linux Laptop Arrives (Phoronix)
    Soft-announced earlier this week was the Kubuntu Focus as a high-end Linux laptop pre-loaded with the KDE flavor of Ubuntu. The Kubuntu Focus produced in cooperation with Mindshare Management, Kubuntu itself, and German manufacturer Tuxedo Computers will officially launch in January and begin shipping shortly thereafter while a review sample arrived in our lab today...

  • MSI DS502 USB Gaming Headset Works On Linux (Phoronix)
    When buying the MSI X299 SLI PLUS for our initial X299 + Intel Core X Series Linux benchmarking from NewEgg it came with the MSI DS502 Gaming Headset as a free gift. Curiosity got the best of me today, and it actually works just fine under Linux...
  • More HDR Display Bits On The Way For The Linux 5.3 Kernel (Phoronix)
    For years there have been open-source developers working on plumbing support for High Dynamic Range (HDR) displays into the Linux desktop stack and it looks like the Direct Rendering Manager driver support is slowly but surely getting there...
  • SteamOS: Desktop vs. Big Picture Mode Benchmarks (Phoronix)
    Curious if running Linux games via Steam's Big Picture Mode causes a performance impact over a conventional desktop session? Here's some benchmarks...
  • Project Darling Is Still Trying To Run macOS/OSX Software On Linux (Phoronix)
    Back in 2012 I wrote about Project Darling as an effort to run Mac OS X software on Linux -- to Wine is for Windows software on Linux, Darling is for Mac software on Linux. Work on Darling seems to have picked up recently after a brief hiatus...
  • Antergos: An Easy, Quick Way To Try Out Arch Linux (Phoronix)
    I decided to give Antergos a whirl to see how this Arch Linux variant works. For those pressed for time or looking at an easy path for setting up an Arch Linux installation, Antergos seems to get the job done well.
  • The Massive Linux Benchmarking Setup Is Chugging Along (Phoronix)
    It's going on one month now that our massive new server/benchmarking Linux and open-source benchmarking farm has been operational. So far things are going great and continuing to churn out a lot of performance data for the very latest Git code of the Linux kernel, Mesa, LLVM/Clang, and other projects on a daily basis...

  • EXT4 & Btrfs Regressions In Linux 2.6.36 (Phoronix)
    Recently when benchmarking the Btrfs and EXT4 file-systems we were left surprised that the performance of the next-generation Btrfs file-system had regressed against EXT4 to the point where the evolutionary file-system is measurably faster in a greater number of disk benchmarks. In fact, even with solid-state drives and Btrfs offering an SSD optimized mode, it still conceded to EXT4. It turns out that in the Linux 2.6.35 kernel, Btrfs regressed. This regression should have been fixed with the Linux 2.6.36 kernel, but recently when benchmarking EXT4/Btrfs against ZFS-FUSE on a 2.6.36 development snapshot we found its performance to still be poor for Btrfs compared to EXT4. To confirm where these two most prominent Linux file-systems are at right now, we have new EXT4 and Btrfs performance results from the Linux 2.6.34, 2.6.35, and 2.6.36-rc3 kernels.


  • Ringing In 2020 By Clang'ing The Linux 5.5 Kernel - Benchmarks Of GCC vs. Clang Built Kernels (Phoronix)
    One of the interesting milestones this year in the compiler world was the ability with LLVM Clang 9.0 to compile Linux 5.3+ for x86_64 without needing any extra patches to either the kernel or the LLVM/Clang compiler. That initial support in Linux 5.3 was not without a few issues, but on Linux 5.5 the experience is in great shape with the stable Clang compiler.
