Last month after Microsoft began publishing their Windows Insider Preview builds of Windows 11, I ran some early Windows 11 benchmarks against Linux using an AMD Ryzen 9 5950X. Linux led in those benchmarks on the AMD Zen 3 desktop while for those wondering if that still holds true for Intel hardware, here are benchmarks of a Core i9 11900K "Rocket Lake" desktop with Windows 10 21H1, Windows 11 in its latest preview build as of testing, and then compared to Arch Linux / Clear Linux / Ubuntu.

Audio/video encoders and decoders are one of the areas where usage of the Rust programming language has increasing interest for speed and safety. One of the most promising Rust-written encoders at the moment is Rav1e for AV1 video encoding and it's now working towards its v0.5 release...
