While pigz compression ratio at 3.060 is just behind zstd at 3.172.

Multithreaded gzip via pigz default compression level 6 just edges out zstd default compression level 3 in terms of compression speed 143.36MB/s vs 122.50MB/s and is much faster for decompression at 284.70MB/s vs 90.24MB/s.

For zstd compression with default level 3 compression had 122.50MB/s compression speed and 90.24MB/s decompression speed with compression ratio = 3.172 for original to compressed ratio size.

Plzip default level 6 compression had 11.51MB/s compression speed and 206.26MB/s decompression speed with compression ratio = 4.225 for original to compressed ratio size.

For lzip compression, multithreaded lzip via plzip was fastest.

Pxz default level 6 compression had 9.45MB/s compression speed and 70.43MB/s decompression speed with compression ratio = 4.277 for original to compressed ratio size.

For xz compression, multithreaded xz via pxz was fastest.

Pbzip2 default level 6 compression had 62.77MB/s compression speed and 172.76MB/s decompression speed with compression ratio = 3.792 for original to compressed ratio size.

For bzip2 compression, multithreaded bzip2 via pbzip2 was fastest.

Pigz default level 6 compression had 143.36MB/s compression speed and 284.70MB/s decompression speed with compression ratio = 3.060 for original to compressed ratio size.

For gzip compression, multithreaded gzip via pigz was fastest.

Round 3: Compression Comparison Benchmarks: zstd vs brotli vs pigz vs bzip2 vs xz etcįor a Intel Core i7 4790K with 4 cpus + 4 hyperthreaded cpus = 8 cpu threads total the findings are as follows:.

The test data set was taken from Silesia Compression Corpus zip file here turned into a tar archive for compression tests. pxz v5.2.2 - multi-threaded version of xz.plzip v1.8 – multi-threaded version of lzip.lzip v1.21 – based on LZMA compression algorithm.lbzip2 v2.5– multi-threaded version of bzip2.pbzip2 v1.1.13 – multi-threaded version of bzip2.pigz v2.4 - multi-threaded version of gzip.brotli v1.0.7 - Google developed Brotli compression algorithm.zstd v1.4.0 - Facebook developed realtime compression algorithm here.added zstd negative compression levels -4 to -1 for faster compression speed at the expense of compress ratio.Zstd supports compression using gzip, lz4 and xz if detected support is available. added zstd -long (for 128MB window size), -long -adapt (for 128MB window size + dynamically adaptive compression level based on perceived disk I/O conditions), -format=gzip, -format=lz4 and -format=xz compression tests.updated brotli from 1.0.5 to 1.07 google/brotli.updated zstd from 1.3.8 to 1.4.0 facebook/zstd.In round 3, updated the following versions: You can read up on round 1 benchmarks here and also tar gzip vs tar zstd benchmarks here and round 2 benchmarks here.

This is round 3 comparison compression & decompression test benchmarks.
