Welcome to iMore! Well, your Mac is six years old. It's understandable that it's slow. You might try to run a system recovery and return your Mac to factory defaults but you may lose stuff saved on your hard drive, depending on how you have things stored and backed up.

Also, if you can increase the amount of RAM, do so.
