Parsing/extracting from a binary QByteArray

[marcvanriet]

I read in ... that the system might run faster if I used the native int instead of the smaller integers. Supposing for a second that speed's more important than memory, would it be worthwhile to re-cast the records into a struct of native integers after importing?

That won't speed up the reading part of course.

It may only be usefull if you run complex numerical algorithms on the data (for instance image manipulation, fourier transforms, color space transformations, ...).

It won't make a difference if you're just displaying the data in a graph or logging the data in a report or so.

Best regards,
