+When using ``apache-airflow>=2.0.0``, :ref:`DAG Serialization <apache-airflow:dag-serialization>` is enabled by default,
+hence Webserver does not need access to DAG files, so you can turn off ``git-sync`` for Webserver by setting
+``dags.gitSync.excludeWebserver`` to ``true``.
+This is also recommended when enabling DAG Serialization for ``apache-airflow>=1.10.7,<2``.

Review comment:
       For Airflow 1.10.9 and earlier, DAG files is still needed for DAG code ttab. For Airflow 1.10.10 and newer (including 2.0.0), it is needed to enable`store_dag_code` to `True` (default value: `False`). DAG Serialization is not enough.
