Why is the Miliki compression time longer than that for ZIP for some files?
Miliki uses over 30 different compression schemes (versus just 1 for ZIP). The application has to analyze every data file and decide on the best scheme for different parts of the data. This is where there is a small penalty for the encoding time. For example, in the case of an Excel or a PDF file, Miliki decomposes the file into its component images, text, formulas, tables etc. The optimal compression scheme is then selected for each of these components. There is a cost paid in processing time for this decomposition process. The ultimate benefit is the reduction in the size of the compressed data. Furthermore, the extra processing time is a tiny fraction of the time it would normally take to transmit a much larger file through a narrow bandwidth. The supreme compression achieved with Miliki saves transmission time and optimizes the space on storage devices.
