Given the recent release of Arch Linux based EndeavourOS and a Phoronix Premium supporter recently pointing out SalientOS as another interesting Arch-based Linux distribution, here are benchmarks showing how these easy/quick to deploy Arch based operating systems with sane defaults compare to that of Ubuntu, Fedora Workstation, and Intel's own Clear Linux. This round of February 2021 Linux benchmarking was carried out on an AMD Ryzen 9 5900X desktop stemming from premium member feedback.

Released yesterday was the Linux 5.10.17 LTS kernel and what makes this point release a bit more notable than usual is that it backports the CPUFreq patches from 5.11 that were used for addressing the earlier AMD performance regression on Linux 5.11 and often leading to net improvements as well over prior kernel series. The CPUFreq patches were back-ported while the AMD frequency invariance support was not, so what does the performance look like for the Linux 5.10 LTS kernel? Here are some benchmarks...

XWayland 21.1 is moving forward as a standalone XWayland release separated from the X.Org Server. Given that X.Org Server 1.21 isn't moving toward release with no one stepping up to oversee that long overdue update, Red Hat engineers have devised the plan for standalone XWayland releases that are separated from the rest of the xorg-server code-base to at least get the updated X11 client on Wayland support out to users...
