'-9' - MAXIMUM COMPRESSION [68020/68030 and 68040/68060 REGISTERED VERSIONS ONLY] This option causes LZX to use its "maximum compression" mode; this mode is completely output compatible with LZX's other compression modes. In this case, the compression parameters have been tweaked to provide the maximum possible compression, at the complete and utter expense of speed. The improvement in compression from the -3 to the -9 mode is invariably 1.5 to 3 times larger than the improvement from the -2 (the default) to the -3 mode. However, the -9 mode is between 2 and 8 times as slow as the default compression rate, depending on the type of file being compressed. The decompression speed is unaffected, and is as fast as ever for files compressed with the -9 mode. The -9 version is provided for distribution-type applications, where the data is compressed once (usually on a fast machine!) and is then distributed online or on disk. The -9 mode is slow enough that it is impractical for casual day-to-day use, but is useful when the absolute maximum degree of compression must be attained. Typical applications for the -9 mode are recompressing BBS file directories to save disk space and make files smaller for users to download; to distribute online magazines; to distribute FidoNet nodelists; or to cram as much software as possible onto a disk. The Benchmarks section contains test data using the -9 option. VALIDITY This option is valid with the following commands: a (add) u (update)
