I use Insomnia on Windows. When I unfold the app, I need to wait 10-15 seconds till it gets unfrozen and after it I can slowly click some buttons and do something. It consumes over 5 GB RAM and it's literally impossible to use if a browser or IDE is opened. Closing other tabs doesn't help reduce memory or speed up the app at all. I have only 50-100 endpoinds and can't really understand what's wrong with the application.
