Deploying code in debug vs run as startup

[MaxMax161]

Our team has used LabVIEW for many years and there are some things that I'm sure labview is capable of but we're not doing that would make life better.

For instance whenever we build the project and run as startup it takes only a few seconds to deploy but loading debug code to the robot takes roughly ten minutes (when running robot main). Why is there such a difference between these two methods of deploying the same code? Is there anyway to make deploying faster?

I also noticed that when we run robot main to deploy the code in debug mode every vi.lib is deploying as well. Why do all these need to deploy as well if they're not changing? Is it so I can debug them the same way I debug the code we wrote? Can I choose to not debug them and make the code deploy faster?

When we build the code before running as start up how much compiler optimization is actually happening? Will any of these optimizations (if there are any) ever produce a noticeable difference in how the code runs?

When we deploy code in debug mode we always run robot main and deploy everything. If I just wanted to deploy a few .vis could I just run them? What kind of problems might I encounter? I know there is an easy way to test this but I haven't had an opportunity since I had the question.

I know there's a lot of questions here and anyone shedding some light on even some of them would be wonderful.
