Complex Workflow Problem

### Custom Node Testing

- [x] I have tried disabling custom nodes and the issue persists (see [how to disable custom nodes](https://docs.comfy.org/troubleshooting/custom-node-issues#step-1%3A-test-with-all-custom-nodes-disabled) if you need help)

### Expected Behavior

When starting comfyui, a workflow containing a lot of plug-in nodes is loaded. After clicking Run, it takes a long time to start execution. What is the reason for this? Is it caused by the need to load "workflow template"?

### Actual Behavior
