Cache Aware Scheduling Shows Nice Wins for AMD Zen 5 on PostgreSQL, Valkey

Cache Aware Scheduling, a long-in-development Linux kernel feature expected to land in Linux 7.2, shows significant performance improvements for AMD processors like the Ryzen Threadripper by optimizing how tasks are scheduled to share cache domains. The scheduler improves cache locality by colocating tasks that share data to the same last-level cache (LLC), reducing cache misses and improving performance on applications like PostgreSQL and Valkey.
