How to Use Chrome Task Manager to Find Out Which Tab is Consuming More CPU and Memory

Categories: posts

Google Chrome has a built-in task manager to help users find out the runtime statistics of each tab. When you open up too many tabs and what to kill some of them to release more memory or CPU, task manager is a great tool. Let’s dive in.

Open Task Manager

You can access Task Manager by clicking on the three-dot icon on the right side of the address bar, going down to More Tools and then select Task Manager.

Kinds of Tasks

There are some different kinds of tasks, some are hidden, and most of them are ordinary visible tasks mapping to a web page.

  • Browser: This task is the manager of all other tasks and it takes care of all network activities. There is only one Browser task.

  • Tab: Each Tab task represents a tab. This is the type of process you want to end when Chrome is under high load.

  • Subframe: subframe is a frame or iframe element inside a web page.

  • GPU Process: GPU process is for GPU accelleration.

  • Utility: some helper services, such as upgrade service, audio service.

Sort Tasks and End a Process

Chrome displays four basic indicators by default. They are CPU, memory, network and process ID. Most of time they are enough for ordinary people.

To sort tasks by an indicator, click on the table header for that column.

When you do want to kill a task, select the row for that task, and click on the End Process button. This will immediately end that tab and release resources taken by the process.

Remember, you will not be able to end the Browser process. To end the browser, simply quit Chrome.

Apart from the basic indicators, you can investigate more runtime information about a process by right clicking on the table. Many of them are very technical.
