What is the size of 'file'? If it is about 640 MiB, no more than 10 
threads can be used to compress it at level -9.

To use 32 threads you need either 'file' to be 2 GiB long or level to be 
at most -6 (for a 640 MiB file).

As you can read in plzip's homepage, "On files large enough (several 
GB), plzip can use hundreds of processors. On files of only a few MB it 
is better to use lzip."


Best regards,
Antonio.
