Right now, teleop runs every ~100-200ms (measured with "Elapsed Times.vi"). This is a huge problem when we are shooting and need our two wheel motors to spin at exact and fast speeds. Although at this point in the season we aren't adding much code, the problem seems to be getting worse. It also may be worth noting that we are using the LabVIEW 2016 Vision Example to find the goal coordinates, although it is disabled with a global variable when not in use.
Does anyone have any fixes/ideas/suggestions/tips as to how to speed up our code?

So one of things that you can do is remove all the get/set refnums in you're project and bundle them together like you have done but make it a type def. I'm currently busy with other things so I do apologize if I'm not going into very much detail, I'll sit down a write a proper response to your request however I will leave you with a link that another user had passed along to me when I was trying to optimize my code. Hope this helps!
