... thus confirming that, indeed, this is an I/O-bound process that benefits quite substantially from parallelism at (at least...) a factor of x4. As would be expected.

Even with the code and evidence right there for your inspection, you draw completely the wrong conclusion.

{blah} In this way, each utility could be told to process a segment of the file.

Prove it by posting the code. You won't (because you can't). Talk is cheap (and in your case invariably wrong!).

What makes my code work is that all the IO is sequential. And that requires shared state.
