+# processStats
+
+> Collect memory statistics about the system as well as the current process (either
+> the main process or any renderer process)
+
+```js
+import {processStats} from 'electron';
+
+processStats.getProcessMemoryInfo();
+>>> Object {workingSetSize: 86052, peakWorkingSetSize: 92244, privateBytes: 25932, sharedBytes: 60248}
+```
+
+## Methods
+
+The processStats has the following methods:
+
+### getProcessMemoryInfo()
+
+Return an object giving memory usage statistics about the current process. Note that
+all statistics are reported in Kilobytes.
+
+* `workingSetSize` - The amount of memory currently pinned to actual physical RAM
+* `peakWorkingSetSize` - The maximum amount of memory that has ever been pinned to actual physical RAM
+* `privateBytes` - The amount of memory not shared by other processes, such as JS heap or HTML content.
+* `sharedBytes` - The amount of memory shared between processes, typically memory consumed by the Electron code itself
+
+### getSystemMemoryInfo()
+
+Return an object giving memory usage statistics about the entire system. Note that
+all statistics are reported in Kilobytes.
+
+* `total` - The total amount of physical memory in Kilobytes available to the system
+* `free` - The total amount of memory not being used by applications or disk cache
+
+On Windows / Linux:
+
+* `swapTotal` - The total amount of swap memory in Kilobytes available to the system
+* `swapFree` - The free amount of swap memory in Kilobytes available to the system
