Left uncompressed and rzip prepared. + +The major disadvantages are: +1. The main lrzip application only works on single files so it requires the + lrztar wrapper to fake a complete archiver. +2. It requires a lot of memory to get the best performance out of, and is not + really usable (for compression) with less than 256MB. Decompression requires + less ram and works on smaller ram machines. +3. It works on stdin/out but in a very inefficient manner generating temporary + files on disk so this method of using lrzip is not recommended. +4.
