RdRand Performance As Bad As ~3% Original Speed With CrossTalk/SRBDS Mitigation

Following today's disclosure by Intel of the CrossTalk/SRBDS vulnerability that is MDS-based and vulnerable across physical cores with affected instructions, Intel released new CPU microcode to mitigate the most prone/significant instructions. I've been benchmarking the impact of this new microcode on multiple systems and will have a full report tonight or tomorrow morning... But here is a look specifically at the look at the impact on the RdRand performance.

An Early Benchmark Of The NVIDIA CUDA GPU Performance On WSL2

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.

Futex2 Proposed In Latest Effort For Linux Kernel Optimization That Can Benefit Gamers

Last year Valve in cooperation with consulting firm Collabora published their work on extending the futex system call for more optimal thread pool synchronization with a means of waiting on any of several futexes. This kernel-level work paired with patched user-space for Wine/Proton allows better matching behavior on Windows. It's been months since hearing anything on Valve's futex effort while today a futex2 system call was published for discussion.

There's A Proposal To Switch Fedora 33 On The Desktop To Using Btrfs

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.
