>                 URL: https://issues.apache.org/jira/browse/AIRFLOW-2027
>             Project: Apache Airflow
>          Issue Type: Improvement
>          Components: scheduler
>            Reporter: Dan Davydov
>            Assignee: Dan Davydov
>            Priority: Major
>
> The scheduler loop sleeps for 1 second every loop unnecessarily. Remove this sleep to slightly speed up scheduling. It can add up since it runs to every scheduler loop which runs # of dags to parse/scheduler parallelism times.
>  
> Also remove the unnecessary increased file processing interval in tests which slows them down.
