+   :term:`BB_LOADFACTOR_MAX`
+      Setting this to a value will cause bitbake to check the system load
+      average before executing new tasks. If the load average is above the
+      the number of CPUs multipled by this factor, no new task will be started
+      unless there is no task executing. A value of "1.5" has been found to
+      work reasonably. This is helpful for systems which don't have pressure
+      regulation enabled, which is more granular. Pressure values take
+      precedence over loadfactor.

    :term:`BB_LOGCONFIG`
       Specifies the name of a config file that contains the user logging
