System Information
Operating system: Windows-10-10.0.19044-SP0 64 Bits
Graphics card: GeForce GTX 760M/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 425.31

Blender Version
Broken: version: 3.1.2, branch: master, commit date: 2022-03-31 17:40, hash: cc66d1020c
Worked: version: 2.93.1, branch: master, commit date: 2021-06-22 05:57, hash: 1b8d33b18c

This issue here is also caused by 7e712b2d6a, same as #97375 (Regression: Creating material node links in python is VERY slow in v3.1).

Short description of error
Setting bpy.data.node_groups["NodeGroup"].inputs- [x].default_value is 29 times slower in 3.1.2 comparing to 2.93.1. It depends on a number of bpy.types.NodeGroupInput present. With a tree with only NodeGroupInput nodes the difference is more than 200 times.

Exact steps for others to reproduce the error
Open the file and run the test script.

This issue here is also caused by 7e712b2d6a, same as #97375 (Regression: Creating material node links in python is VERY slow in v3.1).
Unfortunately, the fix for #97375 (54b293237e) does not improve things here.

@JacquesLucke: do you think there is room for improvement in this case also?
