Single process shared variable without timestamp or local variables

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: https://www.ni.com/en/support/documentation/supplemental/06/using-the-labview-shared-variable.html

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).
