- Linux kernel developers are working on integrating swap cache and swap maps functionality with the swap allocator, leading to the creation of Swap Table.
- Swap Table aims to provide lower memory use, higher performance, dynamic swap allocation and growth, and greater extensibility.
- Engineer Kairui Song from Tencent posted a patch series for Swap Table, implementing design ideas discussed by kernel developers.
- The patches promise a 20-30% performance gain for various workloads and lower idle memory usage.
- The Swap Table patch series consists of 27 patches and is currently under review for potential inclusion in the mainline Linux kernel.
