    Hi, the file doesn’t contain spaces, it’s just one word per line. So the results are the same. If mmap is faster, is there a reason read0 doesn’t use it, or is it just a potential optimisation that hasn’t been implemented?

    It doesn’t really matter as only a couple of milliseconds for even a fairly large file, but it would be nice to have a deeper understanding of the performance of various operations.
