### Godot version

Godot 4.1-beta2

### System information

Manjaro Gnome, Intel Core i7-11800H

### Issue description

On a relatively modern laptop (Intel Core i7-11800H), in a scene with many scripted nodes (total of 900+ with roughly half of them scripted), adding or duplicating a node freezes the editor for several seconds. Godot 4.0.2 handles such scenes much better!

Here is a flame graph captured while repeatedly duplicating simple Marker2D nodes with Ctrl+D in a complicated scene:

Performance data file to use with hotspot v1.4.1 (relevant data starts at the 75-second mark and lasts about 20+ seconds):

### Steps to reproduce

1) Add 1000 nodes with a script attached.
2) Duplicate a node and witness lags.

Also affects scrolling the scene tree dock.
