Linux From Scratch - Version r12.2-760-multilib

Chapter 8. Installing Basic System Software

8.9. Lz4-1.10.0

Lz4 is a lossless compression algorithm, providing compression speed greater than 500 MB/s per core. It features an extremely fast decoder, with speed in multiple GB/s per core. Lz4 can work with Zstandard to allow both algorithms to compress data faster.

Approximate build time: 0.1 SBU
Required disk space: 4.2 MB
