Norppa backend currently runs several cronjobs, which include mailing, database view refreshing and precaching.
Cronjobs can be disabled by setting CRON_DISABLED environmental variable to 'true'. This allows for running multiple replicas of Norppa without e.g. sending the same mail multiple times.

Low = performance optimization or similar: failure could lead to a slight UX degradation
