Comparisons speak for themselves
Various test methods (benchmarks) have been developed in the past to compare the performance of different data compression algorithms.
These test methods all work in a similar way. As a rule, a small quantity is selected from several thousand different data records and files. The principal selection criterion is the condition that the files created by compression must have typical attributes of the data type they represent.
That enables reliable statements to be made about the behaviour of the individual algorithms when applied to data of the particular type.
Figures sometimes say more than words
The following comparison uses a version of the i³ compression algorithm. The Kennedy.xls file from the Canterbury Corpus was used as the test data. For the purpose of comparison the same values were determined by the highest compression stage of the gzip program. gzip is based on the Deflate algorithm, a combination of LZ77 and Huffman coding. In a direct comparison with using gzip, the i³ compression algorithm delivered a data reduction value no less than 88.4% superior.
