I'd like to speed up an animation, Changing FPS doesn't do anything When I try to edit my FPS in my animation, it doesn't affect anything. The animation is very slow and I'd like to speed it up. If you need any files or such to help please ask! BTW: This happened when I started Blender, I didn't change anything.  I just rigged a model and animated it.
If the problem is just your animation speed in the viewport, your computer might be lagging. You can fix this by changing your Playback Sync setting from No Sync to Frame Dropping at the bottom of your screen:
