Patches Provide For Much Faster In-Kernel Zstd Due To Embarrassingly Bad Inefficiency
Recent updates to the Linux kernel have introduced patches specifically designed to enhance the efficiency of Zstandard (Zstd) compression within the kernel. These changes target what has been described as 'embarrassingly bad inefficiency' in previous implementations, enabling faster data compression and decompression operations. As Zstd is increasingly utilized in various systems for data management, these improvements are poised to have broad implications for performance in applications making use of in-kernel compression methods. Developers and organizations that rely on such technologies can expect noticeably enhanced performance metrics following these updates.
