How to Speed up a Chromebook

If you experience a slowdown on your Chromebook, you might want to know about how to speed up your Chromebook. Fortunately, although there are a number of known issues that can cause this laptop to slow down, fixing it is easy.

1. Check the Task Manager


One of the easiest ways to find out how to speed up your Chromebook is to check the Task Manager on your Chromebook.

To access Task Manager, open Chrome, select the three dots at the top right, then select More tools> Task manager.

In the Task Manager window, you can see which applications use the most CPU or memory on your Chromebook. If you see any application here that is the culprit, uninstall it to free up your Chromebook resources and improve performance.

2. Make sure you are not experiencing network problems


Many Chromebook users think their Chromebooks slow down when the real cause might be a network problem. You can rule this out by running a fast network speed test.

Use the online speed test service by opening your Chrome browser and visiting one of the top network speed test services. Run this test to confirm your internet speed is what you expect. These best services include Speedtest.Net,, or

If you want to monitor your network speed on an ongoing basis, you can install the Chrome OS application from the Chrome Web Store. This application lets you check your network speed from within a browser. The best applications include SpeedTest, OpenSpeedTest, or Ookla Speedtest.

If you find your network is a problem, check your router or contact your ISP to troubleshoot your internet connection.

3. Reduce Local Storage Clutter


Another problem that can slow down the performance of a Chromebook is when the local hard drive reaches storage capacity. This can cause errors every time you try to download or create a new file.

Most Chromebooks come with 16GB to 32GB of local storage. It doesn’t take long to download and other files to fill that space without you knowing.

There are several ways to solve it.

  • Add an SD card to your Chromebook if it has an SD slot (mostly done).
  • Change your file download location to cloud storage.
  • Delete files that are often stored in your local storage location

4. Enable Prefetching Pages


Google applies creative technology to make web pages load faster. This is called the prefetch page.

When you enable previous page fetching, Chrome will search through the page you opened for any link, and it will cache web pages that are linked to any link in that page’s links. If you tend to surf the internet by clicking links from one page to the next, this can improve your browsing experience. To set this:

  1. Select the three vertical dots in the upper right corner to open Chrome settings.
  2. Scroll to the bottom of the page and select Advanced.
  3. In the Privacy and security section, make sure the page preload is faster to browse and that search is turned on.

5. Minimize Chrome Extensions and Applications


On a Chromebook, the only application that you can use is the Chrome extension or the Chrome app. But even the Chrome app is technically a Chrome extension that runs in their own window.

Because not all extensions are made efficiently, poorly programmed (or dangerous) applications can cause your Chromebook to slow down. This is why it is always a good idea to scan all installed Chrome extensions and clean them.

To view and uninstall Chrome apps or extensions, open your Chrome browser and type in the location field to open the Chrome Web Store. At the top of the window, select the gear icon> My Extensions & Applications.

This page will display all extensions and applications that you have installed. If you see an application or extension that you no longer use, select Remove from Chrome.

6. Clean Browser Cache and Cookies


Over time, when you visit many websites, browser cache and stored cookies can increase significantly. It is always a good idea to regularly clear cache and cookies to keep your storage clean and keep your Chrome browser (and Chromebook) working at peak performance.

The option to clear browsing history is automatically checked when you clear browsing data. Be sure to deselect this if you don’t want to lose your browsing history.

7. Block Javascript and Ads


Most websites today use Javascript for website and advertisement functionality. Unfortunately, not all websites use this script efficiently, and many more websites use dangerous scripts.

Flash has been a security problem for Chrome for some time, and because of this, Google has disabled Flash support in Chrome. You can take this step further by deactivating Javascript too.

  1. Open Chrome, then open the settings.
  2. Scroll to the bottom of the page and select Advanced.
  3. In the Privacy & Security section, select Site Settings.
  4. Select the arrow next to Javascript.
  5. Disable the selector next to Allowed so the text changes to Blocked.

8. Activate Hyper-Threading


Hyper-threading is when many threads (processes) can run on the CPU. This means that if one process you run “hangs,” your CPU will continue to run another thread and your system will not be locked.

To enable hyper-threading, open Chrome and chrome types: // flags # scheduler-configuration into the location field. On the right drop down, change Default to Enable Hyper-Threading on the relevant CPU.

Note that this feature will only work on Chromebooks with CPUs capable of hyper-threading. You also have to balance the pros and cons of performance versus security risks when activating this.

9. Enabling GPU Rasterization


Google has a list of experimental Chrome flags that can help improve performance. One of them is GPU rasterization. It only unpacks web content processing from your CPU to your GPU. This can help performance because GPU processors are usually quite powerful, and surfing the web rarely requires much GPU processing power.

To enable this experimental feature, open Chrome and chrome types: // mark # GPU rasterization into the location field. To enable this feature, change the dropdown right from Default to Enabled.

10. If All Fails: Powerwash your Chromebook


If all else fails, you might need to reset your Chromebook to factory default.

Powerwash will erase all applications and extensions, and set all Chromebook settings back to factory defaults. You will also lose anything stored in local storage.
