Maybe if you read the entire file into RAM first and then timed just the processing of the bytes.

But I'd wager it's probably limited by the SSD speed and filesystem caching code at this point.

(Would be easy enough for an assembly guru to prove either of us right or wrong!)

The 250ms figure does not include loading the file into RAM. It's just memory access and number crunching.
