## AI overview

The article reports Linux 7.4 patches that defer Zstd stream initialization until the first walk iteration, eliminating redundant initialization. Benchmarks show single-digit compression speed improvements and decompression speedups of 13% on bare metal or 35% in a virtual machine.

## Source excerpt

In addition to Usama Arif's recent Linux patches for addressing a major inefficiency within the Linux kernel's Zstd compression code, he also has a separate patch series destined for Linux 7.4 to further enhance the Zstd compression/decompression performance by avoiding redundant initialization...
