ShaderGraph undo operation takes longer on bigger Shaders

Package: Shader Graph


Steps to reproduce:
1. Download and open the project ""
2. Open the Water2 ShaderGraph (Assets > Shades > Water2)
3. Click on Create Node by Right-clicking inside the ShaderGraph
4. Delete the Node (Right-click the Node and Delete)
5. Notice the time taken to delete the Node
6. Create another new Node
7. This time press Ctrl + Z on Windows or Command + Z on macOS to undo the Node creation

Expected result: Undoing the Node creation takes the same amount of time as compared to deleting the Node
Actual result: Undoing the Node creation takes longer time than deleting the Node

Reproducible with: 7.6.0 (2019.4.29f1), 10.5.1 (2020.3.14f1), 11.0.0 (2021.1.15f1), 12.0.0 (2021.2.0b4)

  1. Resolution Note:

    It's a limitation of our current back end. We're actively in the middle of a refactor to a new back end (Graph Tools Foundation) which may address this issue. We will need to re-test and reassess this test case once the migration to the new back end is completed.
