This is my setup with regard to DAT info sources:

The info-texts are only (re)imported when I update these files (i.e. when I use the command 'touch' to set a new modification date on them). Otherwise data is read directly from the (DAT-info) database (no loading / importing required).

You can force a reimport by clicking on the respective refresh button(s).
