Things you can analyze in memory tab of your activity monitor:

  • Memory Pressure: This part of pane shows you the availability of memory resources. As you can see in the above image. The green one indicates the available resources. The yellow one tells about memory which is partially available. The red one is very important and you should keep an eye on it. It shows you the memory resources being used up while using the apps
  • Physical memory: Ram which is installed on your Mac.
  • Memory used: This gives the exact memory resources currently used up by all the apps and mac os. It is broken into 3 different parts. The first one is App memory which is used up by all the apps. The second one is the Wired memory which cannot be compressed and it always stays in the RAM. The Third one is Compressed, it is the amount of memory compressed to make space in the RAM to run other apps and their processes.
  • Cached files: It is the memory which was used up by other apps but now it is available to be used by any other app. For eg: You are using google chrome and you closed it. The system will have cached file of that. If you open chrome without using any other app. It will open up even faster because of the cached files.
  • Swap used: It is the memory space used for startup drive by the Mac management system.

Energy Tab

If you have a mac laptop then this tab is very useful for you. It tells you which of the apps is using more energy. This can be very helpful when you are out somewhere with your mac and you don’t have your charger. You can close the apps which are consuming more energy and run your laptop for a longer period.

  • Energy Impact: In this tab, you can see the energy all the apps are using and you can close the app which you think is not needed as of now. By doing this you can increase your Mac OS battery lifetime.
  • App Nap: Sometimes we have apps in our system which don’t we are using but they are still open, For eg: Skype. Some of these apps are supported by app nap. That means it will use minimal energy when you are using that app.
  • Preventing Sleep: It tells you which of your apps is stopping your mac to go to sleep.

Disk Tab

Here you can see data of each processes your disk reads and reads out (IO) that is the number of times Mac access the disk to read and write. You can check where your disk space is being used up the most.

Below the pane, you will observe the graph and other things. Here you can the information about the total disk activity of all the processes running. The blue line in the graph depicts the amount of data your Mac disk is reading per second and the red line shows the amount of data written out or written per second.
