How To Solve Google Chrome High CPU Usage Issues


What are the major browsers these days? Well, I would start with Mozilla Firefox, Google Chrome and Internet Explorer. From all of them Chrome is the one that has been launched the most recently. That means there are still a lot of things people don’t know about this web browser. In some forum posts I have read about people complaining because of the high CPU usage made by this app.

From the start, when speaking about this matter I can tell you there are several causes that can produce such an effect. Like for example, when owning a low resources computer, this web browser is simply taxing you. This is because Chrome uses and has a multi-process design, a design which your computer isn’t used to handle. Other reason could be that this app being designed for high end computers, it uses a lot of CPU because of the multiple extensions installed or is running background tasks. To see what happens “back there” simply type “about:memory” in the Chrome address bar. This will bring up a detailed memory statistics and see where your memory is being used.

Let’s take these cases one at a time. 1st we will speak about multiple Chrome processes. If you have used Chrome before, you probably noticed that in the task manager there are multiple instances running. This is an action caused be the fact that Chrome runs several processes. They split between one process for the browser itself and one for each open tab you have running at that time. Also there are several processes that happen for every running plug-in or application involving this product. Although the design is pretty nice and makes the usage very secure, at the same time has the disadvantage of taking up much more memory than other browsers do. And this happens especially if using a large number of tabs and extensions. In order to manage this factor, you can kill Chrome specific tasks with Chrome’s Task Manager. This can be found and opened by clicking on the wrench icon in the upper-right corner. From there select “Tools” and then click on “Task Manager”.

We should focus a little more on this Task Manager option offered by this browser. You should know that for each extension installed Chrome uses a background page. You can see these pages in its Task Manager by going to “Extension:” label fallowed by the extension name. When it comes to tabs you can indicate every one of them by writing “Tab:” and each running plug-in, such as Flash, has its own task as well. Another option that can be seen is the number of pages running at that time. Just look for the item named “Background Pages (10)”. It is obvious that the number in parentheses reflects the actual number of pages running in the background. Modifying this extension can increase or decrease the number of running processes. If you wish to end a task using Chrome Task Manager, it can be done by selecting the process and clicking on “End Process”. When ending a process there should be a notification received that should tell you the process has crashed.

On a number of times I have spoken about background pages that are running. These are the pages that might run even after closing the Chrome browser. As you can probably imagine, these pages continue to use precious CPU resources even if the user doesn’t use them for anything else. This is a setting that can be disabled by typing “chrome://settings/advanced” into your browser’s address bar. So, you will open the Under the Hood settings page. From all those options, scroll down and be sure to deselect “Continue Running Background Apps When Google Chrome is Closed.”

There are some solutions that could easily be used in order to solve some of the problems. Like for example, there is a way to configure Chrome so it would not open so many tabs at startup. Also for a smoother experience remove or disable all extensions that are not a must. The option of disabling, I consider to be the most effective simply because you also have the option of enabling things back. This also lets the user to see which extension are using more resources and only allow those who are worth running. Also, a thing people from Google are recommending is clearing you cache by going to “chrome://settings,” choosing “Under the Hood”. From all the options available here you should click on “Clear Browsing Data.”

I am a Mozilla Firefox user in general but have used Chrome very intensive the past few years. With the right knowledge, this web browser could prove to be the solution you need for every day to day internet browsing.
