GitHub user michaelosthege edited a comment on the discussion: High CPU and database load caused by Airflow 3 dag-processor and scheduler
At 15s idle sleep, all 2 DAGs disabled, and only the PostgreSQL and scheduler running, I get about **30 transactions per second**. In my setup this creates 25 % CPU load from the PostgreSQL container compared to ~2.6 % under Airflow 2.9.0 with webserver, scheduler and DAGs turned on 😮 The corresponding flame graph shows <5 % time spent in `time.sleep`. <details><summary>👀 yet another flame graph</summary>  </details> GitHub link: https://github.com/apache/airflow/discussions/53177#discussioncomment-13735074 ---- This is an automatically sent email for commits@airflow.apache.org.
