Hmm.. The example put up on the github README is a bad test case(for performance comparison), as it does almost no processing on the actual subprocesses. A bet

Hmm.. The example put up on the github README is a bad test case(for performance comparison), as it does almost no processing on the actual subprocesses. A better one could be creating thousands of small files(with dd or something in a directory, though it's io-bound not cpu-bound). Best might be some kind of repeated floating point exponentiation repeatedly.
