1 billion byte text file
A text file with the size of 1,000,000,000 bytes  is compressed using FastLZ-based 6pack compressor  and the de-facto standard zip utility . The time for compression and decompression [5, 6] and the size of the compressed file are compared, giving the following result (shorter is better):
It is obvious that zip can compress better since FastLZ is not optimized for compression ratio, but rather the speed. Although the compressed size of zip is 77% compared to that of FastLZ, FastLZ compresses almost 4x faster and decompressed almost 2x faster than zip, reaching the remarkable compression speed of over 50 MB/s for the above test case.
 Please take into account that benchmark results always depend on the test data. Real-world performance will vary based on system configuration, working data, and other factors.
 It is the first one billion characters of English Wikipedia dump on Mar. 3, 2006. See also test data for large text compression benchmark from Matt Mahoney.

 zip command line archiver is taken from Info-ZIP's zip 3.23. It is executed in the fastest mode, i.e. zip -1.
 Execution time was measured using timer 3.01 utility from Igor Pavlov. Only process time (kernel time + user time) is considered, thereby excluding disk I/O time.
