The Prefetch feature in Chrome takes up resources by caching pages you may never go to. I like to disable it using these steps:
1. Click the Menu button in the upper-right corner, then select Settings.
3. Choose the Show advanced settings… option.
4. Scroll down to the Privacy section, then uncheck the Predict network actions to improve page load performance option.
Now Google Chrome will no longer use resources to try to load data from pages it thinks you may visit.
