The Performance section actively monitors the system-wide CPU and memory usage and represents these graphically as a graph.

The left side bars display total free CPU / MEM available. The graph provides a relationship between the two.

The graph can be customized simply by selecting which bar you wish to graph.

Below the graph is provided a live statistical view of Physical, Page File and Virtual Memory usage. The first column shows the totals, the second represents the amount available, and the final column shows the amount used as a percentage.
