Description
Describe the bug
When working with Prompt Flow in the browser on AzureML (or via AI Foundry), the user interface becomes extremely slow and unresponsive. Our business users rely on the Azure Portal UI and cannot use the CLI. In some cases, making a simple change to the flow can take up to 30 minutes. We’ve observed that Microsoft Edge performs slightly better than other browsers, but the experience is still very poor.
How to reproduce the bug
1. Create a Prompt Flow with more than 4 components.
2. Use the Azure Portal UI to make changes to the flow.
3. Work simultaneously with multiple users in the same workspace.
4. Observe the slow UI response and delays in updating changes.
Expected behavior
A responsive user interface with prompt feedback and flow execution times in seconds, not minutes.
