xz's "extreme" compression option only changes the compressor, the decompressor doesn't even know which level of compression the compressor used. Using extreme compression speeds up decompression because the cpu usage is roughly linear with compressed size.
Using extreme compression uses more rigerous compression without raising the size of the dictionary as using -7, -8, or -8 (64MB)--see xz(1) for more info. -- -Shawn Landden -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble? Contact [email protected]
