Preload Top Hit In the Background

If Safari sometimes seems sluggish when you are typing in the address field, try turning off Safari Preferences, Preload top hit in the background. When you have this feature on, and you type the name of a website you have bookmarked or that is in your history, Safari will start to load the page even before you hit Return. For most people, this will speed up web browsing. But if you have a slow connection or often type similar searches looking for different results then it can be useful to turn it off.
