Quite interesting. Although I vaguely knew about the MCE module(s) before, I have never tried to use it/them, because I had the feeling that it would not bring much benefit when reading only one very large file (my input files are often gigabytes or even tens of GB large). It appears from your example that I was probably dead-wrong.

I should probably give it a try. Although one of my problem, presently, is that I am currently stuck with very old versions of Perl (5.8) (because of the AIX and VMS versions I am working on), so that dependencies might be fairly difficult to resolve.

But, having said that, we should move relatively soon (hopefully just a few months) to new hardware (blades) with much more recent versions of Linux, thus enabling much more recent versions of Perl. If not now, at least then, I might be able to take advantage of the MCE module(s).

Thank you for the information.
