PostgreSQL was showing off some incremental gains when running on the newer Linux kernel versions. Compared to Linux 6.6 LTS, the difference against Linux 7.1 upstream becomes rather significant with the many small kernel enhancements since 2023.

ctx_clock benchmark with settings of Context Switch Time. Linux 7.1 05-14 was the fastest.

This System76 Thelio Major workstation is yet another system showing lower context switching time on Linux 7.1. In other Linux 7.0 vs. 7.1 benchmarking, other AMD systems have shown similar improvements.

nginx benchmark with settings of Connections: 500. Linux 7.1 05-14 was the fastest.

The Nginx HTTPS web server performance has kept evolving nicely with succeeding Linux kernel upgrades.

Llama.cpp benchmark with settings of Backend: CPU BLAS, Model: gpt-oss-20b-Q8_0, Test: Prompt Processing 2048. Linux 6.6 LTS was the fastest.
Llama.cpp benchmark with settings of Backend: CPU BLAS, Model: MiniMax-M2.5-UD-TQ1_0, Test: Text Generation 128. Linux 6.6 LTS was the fastest.
