Intel Granite Rapids WS Core Scaling Performance With The Xeon 678X

26 août 2026 à 16:20
Last week I provided a look at the Intel Xeon 600 series Hyper Threading performance with the Xeon 678X "Granite Rapids WS" processor for HT/SMT on and off. That was interesting while another reader request was to look at the CPU core scaling performance for this high-end workstation processor. Here are those benchmarks for showing the performance, power, and frequency/thermal impact of the Xeon 678X when limited to 6 cores, 12 cores, 24 cores, 48 cores, and then the 48 cores + HT default configuration.

AMD Proposes New LLVM iTHP Option For Squeezing More Performance

26 août 2026 à 14:49
AMD's compiler team is proposing a new LLVM Clang compiler option, -fenable-readonly-thp for implementing instruction Transparent Huge Pages "iTHP" at compile and link-time. With -fenable-readonly-thp, they are finding more performance out of SPEC CPU, Geekbench, and other workloads from the arranging of 2MB segment alignment at link time and allowing the executable text range can be promoted to huge pages...

Fedora + Tuned-PPD Performance Regression Should Be Fixed With New Linux Kernel

26 août 2026 à 14:13
Earlier this month when benchmarking six Linux distributions on the new Framework Laptop 13 Pro powered by Intel Core Ultra Series 3 "Panther Lake", the performance was strangely slow on Fedora Workstation 44. When digging further into it, the performance loss was with Fedora 44 using Tuned-PPD by default where as other Linux distributions default to Power Profiles Daemon. Ultimately, after Red Hat engineers got involved, was found to be a bug within the Intel P-State kernel driver exhibited by Tuned-PPD. The latest Linux kernel already has a fix in place and will be back-ported to Fedora 44...

Linux 7.0-mk2 Released For Multi-Kernel Linux With Promising Performance Results

25 août 2026 à 21:30
Last year a multi-kernel architecture was proposed for the Linux kernel to allow multiple independent kernel instances to co-exist on a single physical machine. Each kernel with "multikernel" Linux can run on dedicated CPU cores whole sharing the underlying hardware resources. Linux 7.0-mk2 released today with the kernel patched for this multi-kernel behavior...

Wayland Found To Be "Intrinsically Faster Than X11, But Not Necessarily More Efficient"

25 août 2026 à 17:37
The PorteuX Linux distribution focused on being a high performance, modular, and minimalist distro took to forking Xfce's xfwm4 window manager into "xfwm4-gl" for OpenGL compositing support. As part of that they developed a window manager / compositor benchmark for evaluating the performance and efficiency of typical operations. Their results are fascinating...

Benchmarking Some Incredible Performance Gains With Btrfs On Linux 7.3

25 août 2026 à 14:18
With the Btrfs pull request for Linux 7.3 having delivered more performance optimizations with some ~3x and ~5x gains mentioned in specific areas, I was eager to test out the new Btrfs performance on the in-development kernel. In today's article are some benchmarks of Btrfs on Linux 7.2 stable compared to Linux 7.3 Git with some very enticing performance gains confirmed in various workloads.
