This needs resolved. I'm sorry, but I have found numerous identical topics relating to this same issue in InDesign dating back the past few years. All of which end up getting 'solved' and closed which I guess stops people being able to add a comment so it looks like less of a problem. This is a major issue accross multiple versions of InDesign and it shows the underlying problem is simply not being fixed. I'm on a top spec laptop which breezes through 500mb+ PSD files so it is not an issue with my PC.
It's ridiculous that in 2020 I need to turn my network and internet off to get InDesign to work. No other Adobe apps display this behaviour so it is an innate InDesign bug.
If anyone else is experiencing this extremely slow behaviour, try turning the network off.
