VI Reference vs. Sub-VIs

[FightOnSCTrojan]

I wanted to hear from the users in this forum about the pro/cons of Opening VI as a reference, as opposed of simply calling it as a sub-VI. I am interested in performance and best cases to used one over the other.

 

Thanks in advance,

You can call up multiple copies/clones of a VI using vi server. This is a good solution if I don't know beforehand just how many times I'll need a particular piece of code or if it might change during normal operation of the application.

Provided you open the refs once ahead of time the performance differences are so small it would be hard to measure.

Suprising?

That is exactly (well sorta) what LVOOP does with dynamic dispatching.

I have to tip my hat to those LabVIEW R&D people. It makes my head spin thinking about "How did they do that?"
