With the Memory tool, you can examine the amount of memory used by an individual process or the entire device.
Memory, like other computing resources, is finite. Checking the memory usage of a process or device can uncover implementation errors and unexpected behaviors.
Use the Memory tool to help monitor CPU usage.
Click the Memory tab to see the device’s overall memory usage.
The Memory tool can display the memory usage of any process on the system instantaneously.
In the Memory tool, you can do the following:
Each process in the Memory tool lists the following information:
Private memory: the total memory used by only this process.
Private plus shared memory (P+S): the process private memory plus the total memory it shares with other processes.
Private plus scaled-shared memory (P+SS): the process's private memory, plus the total memory it shares with other processes divided by the number of processes sharing that memory.
For example if a process's private memory is 1Mb and it shares 1Mb with three other processes, its private plus scaled-shared total is 1.25Mb.
