in thread is this the most efficient way to double-parse a large file?

1/2 could be almost any number. The reply was more to shake up your thinking a little to make you think more in terms of "let's try the simple way first". Remember: premature optimisation is the root of all evil.

The important rule of thumb is: "If the code changes take longer than the run time saved, it's fast enough already".

If the code changes take longer than the run time saved, it's fast enough already.
