Today we have rolled out the default kernel to be optimized out of the box with #AutoFDO. AutoFDO is a PGO like optimization technique and should improve the performance of the kernel between 1-2% across most workloads.

I'm slowly working through a reading queue of modern forays into non-deterministic compilation and optimization techniques.
It's actually really cool to see positive results for learned optimization policies beyond autofdo.

Clang AutoFDO + Propeller Optimization Support Merged For Linux 6.13
Last night when writing about the Clang AutoFDO and Propeller optimization patches sent in for Linux 6.13 I had wondered whether Linus Torvalds would go through with the pull request given some of his past commentary around aggressive compiler optimizations... But to much delight, this evening Linus Torvalds has merged the Kbuild pull request that introduces Clang-based AutoFDO and Propeller compiler optimization support for allowing greater kernel performance out of tailored (profiled) workloads...

Wow, this is a really big achievement.
Thank you for benchmarking, Michael!
We are going to proceed to improve the performance further of CachyOS - recently we have also rolled out the AutoFDO optimized kernel as default.

Arch Linux Based CachyOS Takes The Lead On Intel Arrow Lake
Following the recent Intel Core Ultra 9 285K Windows 11 vs. Ubuntu Linux benchmarks I wanted to expand the testing to look at how well other Linux distributions as well were performing on this new 24-core Arrow Lake desktop processor. To much surprise Intel's own Clear Linux distribution didn't take the top spot this round but as a surprising upset the Arch Linux based CachyOS distribution outperformed Clear Linux, Ubuntu, Arch Linux, and Fedora Workstation on this flagship Arrow Lake processor.
