I suggest you try it.

First you should try it on a small file with fixed length records and no delimiters.

When you've worked out why the file ends up empty, and how to fix that, then try it on a 500MB fixed record length file with no delimiters. And if you could time how long it takes and report back that would be interesting.

Don't worry about being too accurate, the nearest week should be fine.

Examine what is said, not who speaks -- Silence betokens consent -- Love the truth but pardon error.
