1-Minute Tutorial to Compression Ratings

This is a summary of the full documentation.

• Comp.Ratings assigns ratings to compressors by their technical merits. The highest rated compressor has the highest compression ratio in relation to the time it needs to compress the data.
• In addition to the standard rating, rating s.e. emphasises speed (fast compressors have high rating), rating r.e. emphasises ratio (slow compressors have high rating). Tables list C/D column in which ratings are assigned for compression and decompression separately.
• Compressors are first tested in qualification rounds. Low rated compressors are discarded and will not be tested further. Most compressors qualify for the full benchmark. (More info about the qualification.)
• Authors submit compressors and instruct they are tested. This guarantees every compressor is correctly tested and make this "an author friendly benchmark". If you are an author and have not yet submitted a compressor, simply write to CR and attach url to your compressor and list all configurations that should be used to test it.
• The benchmark is always up to date. Compressors will be usually listed within 1-2 days from the submission.
