Is this web page using high memory in Safari?


Surfing the web is the new normal now, and I won’t be surprised if you open multiple tabs on your Safari browser. Since adopting the multi-tab functionality, it is easy to open multiple websites and search for relevant details in one go.

But when you open websites, you may see this message appear multiple times: This web page uses considerable energy. This is usually followed by a sub-message indicating that closing this tab can help improve system performance.

Safari browser is very efficient when it comes to resource allocation, but when you open multiple tabs (I’m taking more than 10 tabs) this management can go haywire. A message like this can certainly alarm you, but just how serious it is and what you are doing about it.

I have been using a Mac for 5 years, and this message pops up from time to time. So here is complete guide to fix the problem – This website is using large memory in Safari Mac problem.

Safari can hold many tabs easily, even with 4 GB of RAM. Nonetheless, if your workload is higher then you will start to see performance issues to the point where Safari browser will not be able to open normal websites like Google, Facebook, Reddit, etc. Below are step-by-step troubleshooting methods that will help you stop this message.

Close less useful tabs

Sometimes we can take all the power we have for granted, but the power is not unlimited. You can’t just open 100 tabs in your Safari browser and expect it to work flawlessly. I’m a person who keeps multiple tabs open and toggles between them while working.

Therefore, it is a good idea to close all irrelevant tabs when they are not in use. And in case you want to visit them later, you can always add them to your favorites or put them in your playlist.

Force quit Safari

Some webpages have very buggy code, or I use to call it spaghetti code. It is very rare to have a website with poor code design, but if it does, it will use up all of your PC’s resources. And accordingly, Safari will launch you – “This web page uses considerable energy. Closing it can improve your Mac’s responsiveness” a message.

In this scenario, you can force close the Safari browser and run it again. Any issues with the confused code will be resolved immediately.

Here are the steps to force quit Safari on Mac:

  1. Click it Appleapple logo in the upper left corner.
  2. To select Force quit from the drop-down menu.
    This will open the Force Quit Applications window.
  3. Select the Safari app from the list.Force the window to close the application with the Safari browser
  4. Click it Force quit button.

Relaunch Safari to see if the issue is resolved. If not, try restarting your Mac as a simple restart can fix various issues including this one.

Use a content and ad blocker

In today’s online generation, most websites are inundated with advertisements. These ads use a lot of your PC’s resources, especially in video ads.

Safari is effective at blocking junk code files such as tracking information and advertising information as such. But it’s not perfect, but there are other third-party extensions that can block content to keep CPU usage to a minimum.

Here are the steps to install a content blocker in Safari Mac:

  1. Open the Adblock website on the Safari browser.
    Get AdBlock Plus from the Apple App Store
  2. Download and install the Adblock for Safari Mac extension.

Disable plug-ins

Plug-ins is just a special name for Safari extensions. This is a tiny little program that your Safari browser uses to give you additional functionality. But they can use up a lot of your resources, so I advise all of my friends to limit the installation of plugins to the bare minimum.

Here are the steps to disable plugins in Safari Mac:

  1. Launch Safari browser on the computer.
  2. Move towards Preference… and go to Advanced Settings tab.
    Safari Preferences menu under the Apple logo
  3. Check the box for Stop plug-ins to save power.
    Stop the plug-in to save power in Safari preferences

This will disable all of your plugins that were using browser memory. Now just check the Safari browser to see if the websites will work fine.

Clear browser cache

Browser Cache is a temporary file and storage database in your browser that helps some websites load faster and provide better usability. But if you don’t clean browser cache time, it can slow down your browser and in some cases ruin your browsing experience.

The error message This web page uses considerable energy. Closing it can improve your Mac’s responsiveness can sometimes be fixed by manually clearing the browser cache.

Here are the steps to clear browser cache in Safari Mac:

  1. Launch Safari browser on the computer.
  2. Move towards Preference… and go to Advanced Settings tab.
    Safari Preferences menu under the Apple logo
  3. Check the box Display the Develop menu in the menu bar option.
    Show develop menu in menu bar option in Safari preferencesThis will activate the new Develop tab in the menu bar.

After successfully clearing the cache, all of your websites will work normally. However, you may need to log into the accounts you have recently visited and clear the cookies.

Check mining scripts

Some websites especially mining websites which are using CPU resources at a very fast rate and hence you may receive these error messages. If a website like an online editor or an online tool shows you this message, that’s understandable.

But if a normal website shows you the error message of high memory usage in Safari, it means it needs to use some data mining scripts. Check the website for an online mine detection tool; if it contains mining scripts, do not use the website.

Update Safari and macOS

MacOS developers continue to update the operating system for better resource management, security, and performance. If your device is relatively old and you are using an older version of Mac OS, you should definitely update your system.

Upgrade RAM

RAM and processor are the two main key factors in the performance of your PC. If you have to use a resource-intensive website for business purposes or for your academic research for some reason, you need to upgrade your Mac’s RAM.

Upgrading the processor on Mac PC is not possible because they are soldered to the motherboard and they are quite expensive to upgrade. But you can actually upgrade the RAM to get better performance.
