When you're installing any collection with premium, on the install side of things, there are constant stalls. Doesn't matter the size of the collection.
As an example, on the test version of my team's collection, which is ~500 megabytes:

The install process with premium takes 17 minutes.
If you close Vortex and restart it every time it pauses on a mod this is what happens:

The install process takes ~6 minutes. This is a considerable difference and makes me think there's an issue on the Vortex side of things that could improve.
Here's the same with the closing and opening parts cut out for real install time in Vortex:

Approximately 4 minutes.
We're talking about 4 times less time to finish. Is this done purposefully or an issue in Vortex, and if it is an issue... can it be fixed? It seems to be a delay on the install side of things rather than downloading.
(Just as a fun comparison, it takes 30 seconds to download with premium on wabbajack: https://www.youtube.com/watch?v=M5OQW5kSjXQ)
