Chrome Running Slower? How To Check Memory Usage

Sometimes your Chrome web browser might run slower than expected, but don’t worry, that’s not your computer’s fault—it might be due to an extension which is utilizing too much of your system memory. That’s why you should always install extensions and apps that you’re really going to use.

Let’s say you’ve installed many extensions and now you don’t know what’s exactly slowing down Chrome. You can take a look at the memory consumption of each extension to determine where the problem lies. Fortunately, Chrome has a built-in tool that will display the memory usage of each extension, as well as open tabs. Let’s learn how to open and use this tool.

From the menu icon in the toolbar, go to Tools > Task Manager. For those who prefer a keyboard shortcut, hit Shift + Esc key.


When you open the Task Manager for the first time, it will be very tiny. You can now resize it so that you can read full names of the extensions, along with their memory usage.

You can now sort the task by clicking on Task heading at the top. If you prefer, then you can also sort it by clicking on the Memory heading. This will display the most memory hogging task at the top.

Now that you know which extension is a memory hog, you’d want to get rid of it. Simply disable it or remove it from Chrome. You can also find a similar extension, or an alternative by going to Chrome Web Store, searching for the same extension and switching to the “Related” tab.
