Although a task can own many data spaces, it is important that it reference these data spaces carefully. It is much more efficient for the system to reference the same data space ten times than it is to reference each of ten data spaces one time. For example, an application might have a master application region that has many users, each one having a data space. If each program completes its work with one data space before it starts work with another data space, performance is optimized.
