The delay is most than probably due to an “editor only” feature which allows the hierarchy icons to show the active state of each GraphOwner (white/yellow colors + play/pause icons).
The delay in this case is happening due to the hierarchy panel repainting whenever the active state of a GraphOwner is changing.
This “feature” can be disabled from within the “Prefs” dropdown in the node editor. The option is named “Highlight Active In Hierarchy”.

If the version you are using does not have this option, then you can manually disable this by changing a few lines in the source code in case you can’t upgrade. Simply open GraphOwnerInspector.cs and completely remove or comment out the following line of code at line #18: GraphOwner.onOwnerBehaviourStateChange += delegate { EditorApplication.RepaintHierarchyWindow(); };
Let me know if that works for you and if that was indeed the cause of the delay (which has been reported before to be the case btw).
Thanks.
