Look I know that I probably should not have 200 PDFs open, but Preview should not be consuming 40GB of memory.
Yeah, you shouldn't have 200 PDFs open.
On the other hand, the good news is your Mac still runs fine, consuming 40GB of "memory" even if you've only got 8GB. Since it's just putting it all out to swap on a fast SSD. So why even complain?
What are you talking about? UPDF does it just fine https://updf.com/updf-mac-user-guide/preferences-mac/#3

I'm aware, however it only works like this in theory. In practice, if the Preview gets to like 60GB, the whole system will get slow until I close it.
Takes a while to finish, with the CPU going into overdrive.
But hey, it's useful when you want to Cmd-F through a bunch of scanned pixels.
