Thanks for asking. Happy to help.

When I say "slow", I’m referring to the fixed cost of the I/O overhead --
stuff required just to get the file handle. That is the "expensive" part I was
referring to.

Obviously, avoiding a full scan of a 50MB file saves time. I'm not disputing
that. My point is that once we've paid the latency tax to open the file and
seek to the first block, reading 100 bytes vs 10 bytes is a rounding error.
The biggest bottleneck is the access.
