This is the best summary I could come up with:

As a continuation of last week’s article looking at Linux 6.6 bringing some impressive gains for AMD EPYC Bergamo, over the past few days I’ve also tested Linux 6.5 stable and Linux 6.6 Git on Genoa and Genoa-X processors as well as Intel Xeon Scalable “Sapphire Rapids” in looking at this next kernel version’s performance.

Last week’s article showed that on the AMD EPYC 9754 a variety of database servers, TensorFlow, and other interesting workloads were exhibiting some very nice gains with Linux 6.6 over Linux 6.5 stable.

The Linux 6.6 kernel brings the EEVDF scheduler, workqueue improvements to benefit chiplet-based CPUs with multiple L3 caches like AMD’s wares, and much more.

There are many new features with Linux 6.6 and AMD server CPU performance seems to be benefiting nicely.

Ubuntu 23.10 in its current development state was run across all the tested platforms.

Linux 6.5.1 and 6.6-rc1 were obtained from the Ubuntu Mainline Kernel PPA for easy reproducibility and analysis by third parties.

The original article contains 263 words, the summary contains 164 words. Saved 38%. I’m a bot and I’m open source!

Oh wow, 100% improvements in some cases, that’s no joke.

EDIT: In Nginx, there’s one benchmark where they get tripled performance on the EPYC9754.
