Whether you use DSL, high-speed Cable, or dial-up connections to surf the Internet, your connection speed is only one of several factors that can affect how fast webpages load in your browser. The size of your temporary Internet files (also called your “cache”), is also important.
A cache is the spot in your computer where your browser temporarily stores info from the web pages you visit (like images). The cache allows web pages you revisit to load faster (since your computer already has the images and doesn’t need to re-download them to show you the page). Because of this, setting your browser store more temporary Internet files (giving it a bigger cache) can speed up how fast webpages appear when you revisit them. (This increased speed of loading revisited pages is especially noticeable for dial-up Internet users.)
1. Click the Tools icon (gear icon in upper right on the latest version of IE) and select Internet Options.
2. From the Browsing history section (on the General tab), click the Settings button.
3. Click the radio button next to Automatically and increase the Disc space to use amount to at least 250 MB (more if your computer has lots of space).
4. Click the OK button to save your changes, then OK again to close Internet Options.
