lzbench is an in-memory benchmarking tool that integrates many open-source compression libraries into a single executable to compare their compression and decompression speed and ratios. It compiles all compressors with the same compiler and optimizations for fair comparison.
Use cases
- benchmark compression algorithms on my data
- compare zstd vs lz4 vs brotli speed and ratio
- measure decompression speed of compressors
- find the fastest compression algorithm for my workload
- test compression levels of a specific codec
- benchmark compressors on all files in a directory
When to choose
- you need fair, same-compiler benchmarks across many compression libraries
- you want to pick a compressor based on measured speed/ratio on your own data
- you need reproducible compression benchmarks across platforms
When to avoid
- you need a production compression library, not a benchmarking tool
- you need to benchmark compressors without available source code
- you need file-level or streaming compression benchmarks rather than in-memory
