This could allow the service time to recover if it is being overwhelmed by traffic, but without the to ability to load balance or scale up/outwards, upstream services will need to know to back off. This is automatically disabled when in debug mode. |

When idle but connected, blueapi consumes ~400MB of memory and 1% cpu and may struggle when allocated less. |
