#sequential_start_priority_threshold ⇒ Integer (readonly)

Containers with priority beneath this threshold are put on the second CPU package on systems with two CPU packages if sequential start/stop is enabled. Containers with priority equal or higher than the threshold might be started out of priority order on systems with two CPU packages.

Note that all thus prioritized containers will be put on the second CPU package, and so it is possible to cause imbalance in CPU usage if all the containers are heavy CPU users.

Returns:

  • (Integer)
