Hi, thanks for your quick answer.
They are standard indicators, 2D Arrays mostly. It seems to me, that the data in these indicators are saved, too, right? Well, they just increase the size of the vi, which is not really a problem. I need the indicators for debugging, I'll delete them, when the work is done or I can re-create them if I need to. But the indicators do not affect the saving time that much.
The vis that take a while to save are for serial communication, could that be a reason?
thanks a lot ...
