Long Range Zip (Lrzip)
Lrzip uses an extended version of rzip, which does a first pass long distance redundancy reduction. It uniquely offers a good range of compression methods:
- LZMA (the default algorithm) – this is the Lempel–Ziv–Markov chain algorithm.
- ZPAQ – designed for user-level backups.
- LZO – Lempel–Ziv–Oberhume.
- gzip – based on the DEFLATE algorithm, which is a combination of LZ77 and Huffman coding.
- bzip2 – compression program that uses the Burrows–Wheeler algorithm.
When it comes to the size of the compressed tarball, zpaq offers the best compression.

Methodology used for the tests
We took a 537MB tarball of a popular source package. The tarball was copied to RAM (/dev/shm), and the tests ran in RAM on a quad-core CPU without hyper-threading (Core i5-2500K), with no X server running, and under negligible load.
Each test was run three times with the latest version (at the time of writing) of each multi-core compression tool. The average results are recorded in the charts above. The tests show the relative difference between the multi-core compression tools. They are for indicative purposes only.
Learn more about the features offered by the multi-core compression tool. We’ve compiled a dedicated page for each tool explaining, in detail, the features they offer.
