Sure, why not? With xz -6 you only need to read and process 124MB, with
-1 you have to read 150MB. The decompression algorithm is the same for
both ratios, only change is the archive size and the dictionary used.
The higher the ratio, the bigger the dictionary becomes and the more
memory you'll need for decompression.
