Last year with Linux 5.10 FUSE added DAX support for use with VirtIO-FS. Like with DAX for other file-systems, enabling this direct access mode allows bypassing the page cache. For use-cases when running on persistent memory like devices or VirtIO, having this direct access to the storage device can be beneficial for performance. With Linux 5.17 FUSE is expanding the DAX support to allow per-inode control as well...

It's been a while since last comparing the Apple macOS performance to Linux since in part because the newer Apple Silicon (M1) hardware isn't yet in good enough shape for performance tests on Linux. But for those wondering about the Intel-powered Macs and how the performance of the latest Linux distributions compare to that of macOS 12 Monterey, here are some benchmarks of the new macOS 12.1 up against Ubuntu 20.04.3 LTS, Ubuntu 21.10, and Intel's own Clear Linux.

Since early 2020 Micron went public with HSE as an open-source storage engine for SSDs and persistent memory. The HSE key-value store proved to be extremely performant with the likes of a MongoDB implementation but required changes to the Linux kernel that made it initially a higher barrier for entry. HSE 2.0 shipped in October that no longer required those kernel changes while still offering blistering fast performance. Now to round out the year they have HSE 2.1...

When it comes to the Radeon ROCm GPU software support AMD only officially supports it on SUSE Linux Enterprise Server, RHEL / CentOS, and Ubuntu LTS releases. But Arch Linux already makes it fairly easy to deploy with their third-party packages and now Fedora and Debian have developers also eyeing possible packaging of the Radeon Open eCosystem software for more easily deploying on those distributions...
