Labview execution speed with hidden VIs

[cbudtz]

Hi.

I just updated from LV 8.5 to 2014 and have noticed that upon closing subVIs with heavy front panel updates I do not regain speed as I did in 8.5. IE, it seems like even though both the block diagram and front panel of a subVI have been closed LV is still updating the front panel thus slowing down execution.

Is there a way to disable this?

Is there a difference if the subVIs front panels are not openend at all from the start?

Also, do you see a difference if you close the front panel instead of minimizing it (at least i understand your "hiding the front panel" as "minimizing it")?

I mean close and not minimized. And yes, if I do a fresh load execution is fast.

Do the VIs that you closed have unsaved changes (such as conversion from 8.5 to 2014)? That will keep them in memory.

Can you show us the code of the subVIs?

Do you do things that force the front panel to be in memory?

(e.g. property nodes).

How do you measure the speed difference?

Thanks for your replies. I solved the issue by turning execution mode of the relevant subVIs into subroutines.
