I've observed a huge difference in memory consumption when importing Peek in a project.
I've tested it on a new Unity 2020.1.5.f1, new URP project. I just launch the new project and install the Peek package via Unity's package manager and press Shift+Space to enter "single window" mode.
I'm on Windows 10.
A screen of the project WITHOUT Peek:
1240 Mo of memory used.
A screen of the project WITH Peek:
3921 Mo of memory used.
I've used your asset a little and I found it very usefull. I'd like to work more with it, but for the moment it's impossible (because of memory consumption, ther was a lot of Unity crash). I hope you'll find the issue (or we find, the fault may be mine ...) !
