Suggestion for 2020.2 new linetype feature improvements

Here’s an example of relatively small scene - just a living room and kitchen with furniture. SU file is 150mb in size: Download files(Request access)

See how long it takes Layout to update viewports after making changes in SU. This video that was recorded on my laptop (Asus N580GD with i7-8750H and 16GB RAM, Geforce GTX 1050): http://youtu.be/W_OWhK9mo9g?hd=1

I made a simple change in SU that took about 30s to save and almost a full minute to update viewport inside Layout so ~1:30 in total. Now imagine having to go back and forth several times… And switching between pages is also very slow - see how long it took to do another update and to switch between pages - especially to page 10 in this video: http://youtu.be/Wi7Hiiai8P0?hd=1 - (it took more than 1:30min!)
