In general, every extra piece of UI showing will require more processing power by your graphics card so if you want faster frame rates you'll want to trim it down where ever you can. Text is just another UI element. Each character displayed requires two triangle and an outline is created by drawing 5 additional characters in black behind each character. That can add up if you're displaying a lot of text.
