LZ4 Compression Algorithm Gets Multi-Threaded Update

Slashdot reader Seven Spirals brings news about the lossless compression algorithm LZ4:The already wonderful performance of the LZ4 compressor just got better with multi-threaded additions to it's codebase. In many cases, LZ4 can compress data faster than it can be written to disk giving this particular compressor some very special applications. The Linux kernel as well as filesystems like ZFS use LZ4 compression extensively. This makes LZ4 more comparable to the Zstd compression algorithm, which has had multi-threaded performance for a while, but cannot match the LZ4 compressor for speed, though it has some direct LZ4. From Linuxiac.com:- On Windows 11, using an Intel 7840HS CPU, compression time has improved from 13.4 seconds to just 1.8 seconds - a 7.4 times speed increase.- macOS users with the M1 Pro chip will see a reduction from 16.6 seconds to 2.55 seconds, a 6.5 times faster performance.- For Linux users on an i7-9700k, the compression time has been reduced from 16.2 seconds to 3.05 seconds, achieving a 5.4 times speed boost... The release supports lesser-known architectures such as LoongArch, RISC-V, and others, ensuring LZ4's portability across various platforms.
