- Linux kernel performance improvements with new Swap Table code overhaul.
- Initial patch series by Kairui Song of Tencent introduces Swap Table as kernel's swap cache.
- Redesign aims for lower memory usage, higher performance, and future-proofing.
- Phase one patches show significant performance gains: over 20% in VM scalability, faster kernel builds, and 6-7% higher throughput for Redis/Valkey.
- Swap Table redesign addresses current SWAP management subsystem issues and aims to simplify future feature implementation.
- Testing shows performance improvements across various hardware configurations.
- Hope for upstream acceptance into mainline Linux kernel.
