Right. This is done by the diagnostic technique of writing *new*,
minimal, complete programs that exercise each piece of the functionality
separately.

What happens when you make a smaller program that only reads the file,
and doesn't write any? Or a different program that only writes a file,

Could you please:
* simplify it further: make a minimal version that demonstrates the
difference you're seeing, without any extraneous stuff that doesn't
appear to affect the result.
* make it complete: the code you've shown
I have a simple program to read a text (.csv) file and split it into
several smaller files. Tonight I decided to write a unicode variant and was
surprised at the difference in performance. Is there a better way?
