Intel Core Ultra 7 270K Plus Performance In 340+ Linux Benchmarks
Last month Intel began shipping the Intel Core Ultra 7 270K Plus “Arrow Lake Refresh” desktop processor. This is a mighty interesting processor for the $349 USD price point with more cores and a larger cache compared to the Core Ultra 7 265K and capable of delivering much of the performance of the flagship Core Ultra 9 285K Arrow Lake processor. In today’s article is a look at how well the Intel Core Ultra 7 270K Plus performs under Linux wit … ⌘ Read more

Linux 7.1 Delivers Performance Regression Fix For Sheaves
The Linux 7.1 kernel is bringing performance improvements for Sheaves, the per-CPU caching layer introduced several kernel cycles ago (Linux 6.18) for better efficiency on today’s high core count hardware. Sheaves began as an opt-in feature but since Linux 7.0 is now being used for all caches… ⌘ Read more

WQ_AFFN_CACHE_SHARD Merged For Linux 7.1: Significant Win For CPUs With Many Cores Per LLC
The workqueue changes merged today for the Linux 7.1 kernel are significant for today’s modern high-end processors where there can be many CPU cores per last level cache (LLC / L3 cache). The new WQ_AFFN_CACHE_SHARD affinity scope can reduce some contention on such systems and help achieve greater performance… ⌘ Read more

LLM-Assisted Patches For Linux 7.1 May Have Negative Impact On 32-bit Systems
Code now merged for the Linux 7.1 kernel may provide some negative performance implications for those still running modern Linux kernels on 32-bit hardware. A fundamental change can present cache line alignment and slab sizing implications for 32-bit Linux OS users but will provide for cleaner code with modern 64-bit computing… ⌘ Read more

[$] Removing read-only transparent huge pages for the page cache
Things do not always go the way kernel developers think they will. When
the kernel gained support for the creation of read-only transparent huge
pages for the page cache in 2019, the developer of that feature, Song Liu,
added a\
Kconfig file entry promising that support for writable huge
pages would arrive “in the next few release cycles”. Over six years
later, that promise is still present, but it wi … ⌘ Read more

AMD Ryzen 9 9950X3D2 To Be Priced At $899 USD

Détroit d’Ormuz : le levier caché de Washington
Depuis le 28 février 2026, le détroit d’Ormuz est fermé. Ce détroit, c’est 33 km de large, 20% de la consommation mondiale de pétrole et 1/5e du commerce mondial de GNL. Selon le discours officiel, le passage est verrouillé, et on nous promet la pire disruption énergétique depuis 1973. Cependant, un détail échappe à la […] ⌘ Read more

Open-Source “GreenBoost” Driver Aims To Augment NVIDIA GPUs vRAM With System RAM & NVMe To Handle Larger LLMs
An open-source, independently developed Linux kernel module called GreenBoost aims to augment the dedicated video memory on NVIDIA discrete GPUs with system memory and NVMe storage. The intent here with GreenBoost is a CUDA caching layer to more easily run larger AI models for LLMs that otherwise won’t fit solely in your graphics card’s dedicated vRAM… ⌘ Read more

This work not only benefits modern Intel CPUs but our testing has shown can also provide some very nice gains too for … ⌘ Read more

Linux 7.0 Aims To Replace More Caching Code With Sheaves For “Hopefully” Improved Performance
Introduced to the mainline Linux kernel last year was “sheaves” as an opt-in per-CPU array-based caching layer. Sheaves was merged back in Linux 6.18 and while it started as an opt-in caching layer, the plan is to replace more CPU slabs / caches with sheaves. Queued up for slated introduction in the upcoming Linux 7.0 cycle is replacing more of those caches with sheaves… ⌘ Read more
