Did not spend too much time on the process analyzer yet, but during the one test I made I've seen that

\AppData\Local\Temp\lv.emf

took half of my boot time. Thousands of activities was related to that single file while labview was starting up.

.emf is a picture format, and my lv.emf is this ... 

How many times would one need to load an icon?

Great, it seems we've identified the most important file in the entire distribution.

Apparently, everything else is just a supporting dependency...

So, i renamed lv.emf and things started without issue, but if it helped performance i don't know.
