Summary
Cache Aware Scheduling, a long-in-development Linux kernel feature, is expected to land in Linux 7.2. Recent benchmarks on an AMD Ryzen Threadripper 9980X (System76 Thelio Workstation) show significant performance improvements for modern CPUs, particularly benefiting PostgreSQL, Valkey, and network performance. The feature helps optimize how the Linux kernel schedules tasks across CPU caches, improving efficiency on modern multi-core processors.
