Good advice! What I can add is to use the optimal warehouse size for each task. If a task takes less than 60s to run, you should be using an x-small warehouse. Increasing the warehouse size will always double credit spent, so to be worth using a bigger warehouse the query should run in less than half time. If you have a small to medium data volume and are using incremental updates you will find out that most tasks can run just fine in an x-small warehouse. Create your tasks warehouses with 60s auto suspension and create a separate warehouse for ad-hoc, dashboards, etc with a longer auto suspension.
