### Apache Airflow version 3.1.0 ### If "Other Airflow 2/3 version" selected, which one? _No response_ ### What happened? Loading the grid view for a DAG with <100 tasks took 30 seconds. Specifically this GET request `ui/grid/structure/dag_name?limit=5&order_by=-run_after` This happens repeatedly across multiple DAGs and on multiple Airflow instances. ### What you think should happen instead? I think this should be significantly faster. Possibly it could be progressive, loading only the data required, like the top level task groups to start with? ### How to reproduce I'm not sure exactly what triggers the long load time. It's possible that mapped tasks are a factor, as we use those frequently. Maybe also the number of dag versions? This happens every time we load up the affected DAGs in the Grid View. ### Operating System debian bullseye ### Versions of Apache Airflow Providers _No response_ ### Deployment Astronomer ### Deployment details _No response_ ### Anything else? _No response_ ### Are you willing to submit PR? - [ ] 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.
