Hi, Petr,
Just one quick observation...

Based on some benchmarking I did a couple of years ago (in
Java, if anyone was curious) the performance consequencess of
different I/O buffering schemes (i.e., character-at-a-time,
line-at-a-time, big-buffer-at-a-time, or all-input-at-once)
can easily dominate total run time, swamping any performance
gains from compilation vs. interpretation for file-oriented
(non-compute-bound) processes.
We know what REBOl does about
my-file-data: read %somefile.data
but do you know what type of I/O scheme your collegue's VO
program was using?
