The Bandwidth Hog
Google Chrome employs a variety of tricks to make web browsing feel instantaneous. One of the most prominent is the “Use a prediction service to load pages more quickly” setting (sometimes referred to as page prefetching). When you visit a webpage, Chrome attempts to guess which link you are going to click next based on your history and the page’s structure. It then silently downloads the content of those linked pages in the background before you even click them. When you finally do click the link, the page appears instantly because it is already sitting in your computer’s RAM.
While this makes the browser feel incredibly fast, it comes at a significant cost. Chrome is essentially downloading massive amounts of data (images, videos, and scripts) for webpages you might never actually visit. If you are on a metered internet connection (like a mobile hotspot) with a strict data cap, or if you are using an older laptop with a slow processor and limited RAM, this aggressive background downloading will consume your data allowance and bog down your system performance. You should disable it.
How to Turn Off Chrome Page Prefetching
You can disable the prediction service via Chrome’s performance settings.
- Open Google Chrome.
- Click the three vertical dots in the top-right corner of the browser window and select Settings.
- In the left-hand sidebar, click on Performance.
- Look for the section labelled Preload pages (In older versions of Chrome, this was located under Privacy and security > Cookies and other site data).
- You will see options for “Extended preloading” and “Standard preloading.”
- To completely disable the prediction service, select the option for No preloading.
Chrome will immediately stop downloading pages in the background. Webpages will only download when you explicitly click on a link, saving you significant bandwidth and system resources.
