Why is layout rendering so slow?

Can't remember if I've asked this before, but I'm working on a project where it's really starting to bite me.

Why is the layout sooooo slow to render?

In my case today, I have a (n admittedly very large-- 16x40") canvas and a map frame of the same size. I'm drawing at a pretty detailed scale for something at that size -- 1:300K. No marginalia yet, and the map itself is pretty complicated. So, I get it, I'm asking Pro to do a lot of detail. 

That being said, it's taking 10 minutes to draw or redraw with every. single. change. This is very painful.

I get that Pro is going to struggle the more you throw at it, etc. However, isn't rendering a map frame in the layout basically the same as rendering a Map View at a certain reference scale? My map view is positively zippy by comparison-- I can refresh the entire intended extent with a reference scale set and it takes like 20-30 seconds, instead of several minutes.

So, my question is: What is going on in the Layout view that makes it soooooooooooooooooo sloowwwwwwwwww in comparison to the map view?

This is not the first time I've run into this, nor will it be the last. Layout has serious performance issues once you get bigger than like, 8.5x11" canvas, but even at that size there's a notice difference in performance between it and the map view. Why, and can it be fixed?

This is pretty common in ArcGIS Pro. Most maps I make I do my work in the map itself, and try to stay out of the layout since performance degrades quickly. Loading times get bad.

I found if I do work in the layout and want to adjust the map I try to zoom in close and work in small areas. But yeah, it's not the best especially if you have a lot of labels and other data going on.

You can always pause labeling, or use draft quality to help speed things up. Or turn off anything you don't need to see at the moment.

Cheers,
