pigz is a parallel implementation of gzip that fully exploits multiple processors and cores when compressing data. It is a drop-in replacement for gzip built on zlib and pthreads, portable across Unix-style operating systems.
Use cases
- compress large files faster using all CPU cores
- drop-in gzip replacement for multicore machines
- speed up backup and archive compression
- parallel decompression of gzip files
- compress data pipelines in shell scripts faster
When to choose
- you need gzip-compatible output with maximum compression speed on multicore hardware
- you want a simple, mature, dependency-light CLI tool
- you compress large files or backups regularly
When to avoid
- you need a compression format other than gzip
- you are on a single-core machine where parallelism gives no benefit
- you need a library API rather than a command-line tool
