To evaluate the performance of byte-level patching engine used in PatchFactory to build a difference between two particular versions, we have prepared a comparison table (below) for well-known software products where you can see the original size of the new version files, the full original installation package (available from the author of the corresponding software product), the Update package size (from the author), the difference size (built with the help of PatchFactory), and the result compression ratio of the result difference size (prepared by means of PatchFactory) versus original installation package and uncompressed new version files of a software product.
