ashb opened a new pull request #11373: URL: https://github.com/apache/airflow/pull/11373
This is about is about a 20% speed up for short running tasks! This change doesn't affect the "duration" reported in the TI table, but does affect the time before the slot is freeded up from the executor - which does affect overall task/dag throughput. (All these tests are with the same BashOperator tasks, just running `echo 1`.) **Before** ``` Task airflow.executors.celery_executor.execute_command[5e0bb50c-de6b-4c78-980d-f8d535bbd2aa] succeeded in 6.597011625010055s: None Task airflow.executors.celery_executor.execute_command[0a39ec21-2b69-414c-a11b-05466204bcb3] succeeded in 6.604327297012787s: None ``` **After** ``` Task airflow.executors.celery_executor.execute_command[57077539-e7ea-452c-af03-6393278a2c34] succeeded in 1.7728257849812508s: None Task airflow.executors.celery_executor.execute_command[9aa4a0c5-e310-49ba-a1aa-b0760adfce08] succeeded in 1.7124666879535653s: None ``` **After, including change from #11372** ``` Task airflow.executors.celery_executor.execute_command[35822fc6-932d-4a8a-b1d5-43a8b35c52a5] succeeded in 0.5421732050017454s: None Task airflow.executors.celery_executor.execute_command[2ba46c47-c868-4c3a-80f8-40adaf03b720] succeeded in 0.5469810889917426s: None ``` <!-- Thank you for contributing!
