Description

System Information
Operating system: Windows-10
Graphics card: NVIDIA GeForce RTX 2060

Blender Version
Broken: version: 3.1.0, branch: master, commit date: 2022-03-08 18:16, hash: rBc77597cd0e15 3.2.0 Alpha broken as well.
Worked: 3.0.1

Delete Geometry Node with combination of Armature modifier and a lot of vertex groups suffers a really big performance drop. Hit is significant, dropping the playback from 80fps to 6fps or even worse when more vertex groups are used by the Armature modifier.
Please look at this issue and try to fix it as soon as possible, i'm unable to use 3.1 because of this.

Simple demonstration file, simply open it in both 3.0 and 3.1, the difference is huge.
