How to identify the tabs that consume the most CPU and RAM in Chrome

The browser is one of the programs that consumes the most CPU and RAM on most PCs, which you may have noticed, especially if you use a browser that doesn’t shy away from consuming resources, such as Google Chrome.

If you have a program open, plus multiple tabs in chrome and everything slows down and the PC fan starts to sigh, you most likely want to open the Windows Task Manager to see who is responsible for this insolence.

Here you will find that it is the Chrome browser that is consuming a very high percentage of the CPU and a good amount of RAM. Now if I have multiple tabs open, how can I know which one is using all those resources?

How to find out which Chrome tab is using the most resources

The bad thing about analyzing memory and CPU usage via Windows Task Manager is that it doesn’t show much detail. This way, it is impossible to identify the problematic tab.

Happily, The Chrome browser itself has a built-in native task manager that it gives us all this information.

  • Click on the 3 dot button that you see in the upper right part of the browser.
  • Choose “More Tools -> Task Manager“.

This will open the Chrome task manager, where we can see the individual consumption of each open tab, as well as their names. It also shows the resource consumption of all the extensions we have installed in Chrome.

From here, locating and closing the problematic tabs is as easy as that. For example, if we see that a tab consumes 51.6 CPU, it means that it is using more than 50% of the processor capacity.

To make things easier, you can order all tabs and extensions in the Chrome task manager according to its use of RAM, CPU and network consumption.

Some basic tips to reduce RAM and CPU usage in Chrome

While many of these recommendations are common sense, we often overlook them due to a simple oversight or carelessness:

  • Close the tabs you won’t be using: Each open tab in the browser consumes minimal resources. If you have a lot of tabs, this number increases significantly. So if you close some of them, your PC will notice it right away.
  • Uninstall unnecessary extensions: We often install Chrome extensions to see how they work and end up forgetting about them after a few uses. Extensions also consume resources: uninstalling them helps improve performance.
  • Minify the most demanding websites: Opening a Wikipedia tab is not the same as watching a movie on Netflix or a YouTube video. If you have multiple tabs open with streaming multimedia content, your computer will notice. Only leave open what is absolutely necessary at the moment.

Extensions to reduce Chrome’s RAM and CPU consumption

After all this, if you’re still having trouble reducing the browser’s heavy consumption, you might want to try one of these extensions for Chrome.

  • TooManyTabs: A good tool if you have a lot of tabs and can’t close any of them. TooManyTabs suspends inactive tabs to save disk space and then brings them back when we need them. | Download from the Chrome Web Store
  • One Tab: Last month we already recommended this extension in its version for Firefox. Well, it’s also available in Chrome and works like a charm. If you have many tabs open with this extension, you can unite them all into a single tab. This will avoid the high consumption of resources and you can restore them when you are going to use them. | Download from the Chrome Web Store
