G2-meters measure G2's actual performance, not its capability. For example, the meter
percent-run-time measures how much processing time G2 is using per second. It does not measure the amount of processing time that G2 is capable of using within a second.
Note: All G2-meters put an extra load on the system. They should be used only when needed.
This chapter does not describe G2 memory organization and management. For information on these topics, see Chapter 45, Memory Management.
