[Qt-interest] QSettings (ini) Write and Load actions

[Matthias Pospiech]

I am using QSettings to write and load Applikation Data (mainly 
calibration files) to an ini file.

If construct the QSettings object each time I want to write or read 
from/to the file. The filesize in total is 4 MB.
However I experience that each access takes very long.

So my question is at which point the saving or reading takes place? At 
the deconstruction of the QSettings object?
I am asking, because I am thinking of creating a global QSettings object 
which is only deconstructed at quitting of the application.
