Our recent benchmarks have shown WSL/WSL2 performance on the latest Windows 10 builds to generally be quite good compared to running bare metal Linux. But past the May 2020 Update and on the latest Insider Preview builds is the initial support for GPU acceleration in conjunction with updated Windows graphics drivers. The initial emphasis is on GPU compute with DirectML and for NVIDIA hardware CUDA support as well. Here are a couple CUDA benchmarks that ran gracefully under WSL2 albeit the performance leaves a lot to be desired...

More than a decade ago Fedora was routinely trying to pursue the Btrfs file-system by default but those hopes were abandoned long ago. Heck, Red Hat Enterprise Linux no longer even supports Btrfs. While all Red Hat / Fedora interests in Btrfs seemed abandoned years ago especially with Red Hat developing their Stratis storage technology, there is a new (and serious) proposal about moving to Btrfs for Fedora 33 desktop variants...

As part of our Ryzen 5 4500U and Ryzen 7 4700U Linux benchmarking there have been multiple requests for showing how various Linux distributions run and perform with these exciting Ryzen 4000 series mobile CPUs.
