Also known as “prerendering“, the Prefetch feature in Google Chrome will cache pages that are linked on the web page you are currently on. This allows the page to load a bit faster when accessing it. The Prefetch feature in Google Chrome takes up resources by caching pages you may never go to.
When you typing www.twitter.com on the address bar of Google Chrome, the page actually has been loaded in the background even though you did not press the Enter button yet.It’s called a Page Prediction — a feature to make the page load faster that could potentially enhance user experience. But, there’s a catch. This feature may waste your internet bandwidth for the page you did not visit, and consume additional CPU/Disk usage cycles. Also, could be a privacy issue since some anonymous data and statistics might be sent to the server to make this feature better and more reliable.
Disable the Prefetch feature as you see fit using this tutorial.
1- Click the “Menu” button in the upper-right corner, then select “Settings“.
2- Scroll down and select the “Advanced” option. Scroll down to the “Privacy and security” section,
If you toggle the setting off, Chrome won’t run DNS look ups for links and it won’t preload high priority targets for user actions either.
*Downside to this is that sites that Chrome connects to may write cookies on the system and may read their own cookies; this may happen even if the linked resource is not visited actively by the user.
Note: Browser extensions like uBlock Origin may force the setting to off automatically. You find the option to disable that in the extension’s options. The extension does this to prevent connections from blocked network requests.
