+ <p>Enable or disable scheduler compaction of load. By default
+ scheduler compaction of load is enabled. When enabled, load
+ balancing will strive for a load distribution which causes
+ as many scheduler threads as possible to be fully loaded (i.e.,
+ not run out of work). This is accomplished by migrating load
+ (e.g. runnable processes) into a smaller set of schedulers
+ when schedulers frequently run out of work. When disabled,
+ the frequency with which schedulers run out of work will
+ not be taken into account by the load balancing logic.
