Single process shared variable without timestamp or local variables

[aucman]

Hi!

What is best to use in terms of performance and memory in larger VI with multiple parallel loops. Single process shared variables without timestamp or local variables. I know there are quees, notifiers ect but I wanna know comparison between these two only.

You can get everything about benchmark between Single process shared variables vs local variables here: http://www.ni.com/white-paper/4679/en/#toc1

The quoted paper compares with global, not local variables (sorry, posting by phone, I might have missed something).
I don't think there will be a significant difference, however local variables always need a front panel object that gets updated in the UI thread at regular intervals. A single process shared variable is thus leaner. Why don't you just benchmark it? (See my Sig).
