AMD Zen 5 Cache Aware Scheduling Improves Linux Performance

TL;DR. New Cache Aware Scheduling benchmarks show performance gains for AMD Zen 5 processors on Linux systems, particularly for database and network tasks. - The feature is slated for integration into the upcoming Linux 7.2 kernel release. - Benchmarking on AMD Ryzen Threadripper 9980X demonstrated significant improvements. - Optimized cache locality reduces cache misses, directly benefiting high-performance computing.

• Cache Aware Scheduling (CAS) is nearing release in Linux 7.2.
• CAS improves performance on modern CPUs, including AMD's Zen 5 architecture.
• Benchmarks show CAS enhances PostgreSQL, Valkey, and network performance.
• The technology optimizes data locality by co-locating tasks to shared last-level cache domains.
