ashb opened a new pull request #8952:
URL: https://github.com/apache/airflow/pull/8952


   The scheduler_dag_execution_timing script wants to run _n_ dag runs to
   completion. However since the start date of those dags is Dynamic (`now
   - delta`) we can't pre-compute the execution_dates like we were before.
   (This is because the execution_date of the very first dag run would be
   `now()` of the parser process, but if we try to pre-compute that in
   the benchmark process it would see a different value of now().)
   
   This PR changes it to instead watch for the first _n_ dag runs to be
   completed. This should make it work with more dags with less changes to
   them.
