### Apache Airflow version 3.1.0 ### If "Other Airflow 2/3 version" selected, which one? _No response_ ### What happened? Today, when you attempt to view large dags with complex task groups on the webserver, the page takes a very long time to load. specifically, the total load time = time taken for `ui/grid/structure` + longest `ui/grid/ti_summaries` response. Im seeing cases where `ui/grid/structure` takes minutes to finish. We need to identify ways to speed this up as this prevents dag runs which are already fetched from being loaded. our real world example: <img width="860" height="456" alt="Image" src="https://github.com/user-attachments/assets/a1e5454b-98e1-4a8b-b9ce-89e5f312a724"; /> ### What you think should happen instead? response should be very fast. ### How to reproduce Create a dag with 5000 tasks and complex taskgroups. Tasks can be empty operators... ### Operating System Sles15 ### Versions of Apache Airflow Providers _No response_ ### Deployment Docker-Compose ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [x] Yes I am willing to submit a PR! ### Code of Conduct - [x] I agree to follow this project's [Code of Conduct](https://github.com/apache/airflow/blob/main/CODE_OF_CONDUCT.md) -- This is an automated message from the Apache Git Service.
