Hi all! Currently its only possible to compress tar files with multiple cores using this command: tar cf myfile.tar.bz2 --use-compress-prog=pbzip2 dir_to_compress/ with the standard compresstools its possible to write that way shorter: E.g. tar cjf myfile.tar.bz2 dir_to_compress/ But this does not use multiple cores. It should be possible that a standard option to the shown command for using multiple cores, say, the parallel versions (pgzip/pbzip2) An alternative would be using the multithreaded versions as default and use the single core apps as fallback.
