How to Reduce Chrome CPU Usage

Most of the people are struggling with the problem of Chrome using a lot of CPU space. But you don’t know why it is so, right? So here in this guide, we will let you know how to reduce Chrome CPU usage.

It is a question that our tech experts hear all the time. This article explores four ways to solve your Chrome CPU problem and get back to browsing in peace. 

4 Easy Steps To Reduce Chrome CPU Usage

1) Update Your Browser

Make sure you have the most recent version of Google Chrome by clicking on “Help” and then “About Google Chrome” in the horizontal menu at the top of your browser window. If you don’t, update immediately.

2) Turn Off Unnecessary Extensions

There are many extensions available for Chrome that optimize or add features to it – but they can also negatively impact performance if used improperly. To see which extensions may be affecting your computer, go to chrome://extensions/ and click “Options” next to each extension. You can then select “Keep up to date”, which will update the extensions automatically when a new version is released, or disable them completely by clicking on the trash can icon. 

3) Tune Chrome’s Advanced Settings

If neither of those helped, try these advanced settings for your browser from Google developer Christian Heilmann:

Go to chrome://flags/

Type “Render thread” in the search box and press enter. This will result in a list with different rendering options. Before changing any of them, make sure you’ve switched Chrome completely off and on again (in the menu bar at the top). 

Take your pick from these flags:

  • WebKit-renderer-explicitly-synchronize-before-layout – Makes the browser make sure it has updated all rendering information before doing a layout (more synchronous). This should always be enabled, as otherwise compositing, painting and most other types of UI updates can happen out of sync. 
  • chrome://flags/#enable-ipc-solo  – This forces the browser to use a dedicated process for each plugin renderer. This is intended as a performance increase when having lots of flash or java etc., but it’s also useful if you have a lot of tabs open and want better separation between them.

4) If All Else Fails: Delete Chrome and Reinstall a New One

If updating your browser, disabling extensions, and tuning advanced settings didn’t help to reduce your computer’s Chrome CPU usage, the only option left is to delete the browser entirely and reinstall a brand new copy. This method will not wipe your bookmarks, saved passwords, or search engine preferences. If you’re worried about losing such information, consider backing it up on an external hard drive before reinstalling Chrome all over again.

Why Does Chrome Use so Much CPU and RAM?

How to Reduce Chrome CPU Usage

I have heard people complaining about how much CPU and RAM Chrome uses, but I didn’t really understand why. Is it just because of the extensions that are installed? What functions does Chrome use up so many resources? After doing some research, here is what I found out.

Chrome has an expansive list of features to provide users with a seamless browsing experience. It also provides developers with stability for building web applications on top of the browser’s technology stack including HTML5, CSS3, JavaScript, and others. This comes at a cost: high CPU usage and memory consumption.

Chrome uses multiple processes to separate web pages from one another. This allows for each tab, plug-in/extension, and web page process to run in its own instance with limited access by other processes that may be running on your machine. If a single webpage runs code that crashes the renderer process, it will only crash that particular process and not the entire browser. This allows for a more stable web browsing experience.

Chrome uses multi-core processing to distribute tasks across multiple CPUs that are available on your machine. Each core is used in sequence until it can be determined which ones should handle further work concurrently, then they all do their share of the load together simultaneously using a process known as threading.

Chrome uses multiple processes that are divided into different tasks with each having its own sets of permissions and capabilities, such as accessing your webcam or memory. Each process is lightweight in terms of system resources so it can handle the task given to it quickly and efficiently without bogging down other running programs on your machine. It is possible to change the number of processes that are allowed to run at one time by opening up Chrome’s settings and adjusting the slider under “Show advanced settings.”

Chrome uses GPU acceleration in rendering graphics which is why it can handle some tasks better than other browsers. This allows for things like Google Hangouts, maps, or any website with lots of pictures to load quickly. The downside is that GPU acceleration uses more resources than just CPU, but it doesn’t use nearly as much as having the UI open or running a Flash element on web pages.

If you are experiencing high memory usage in Chrome try closing any unnecessary tabs and browser extensions by right-clicking them and selecting “Close tab” or “Close other tabs.” If you are still experiencing high memory usage, try to restart Chrome.

Chrome is one of the most resource-intensive browsers on the market right now because it has so many features that provide a better user experience to users while keeping developers building advanced web applications using their products and services in mind. It comes at a cost though, so if you feel your computer is running slow, try closing a couple of tabs and see what happens.
