What OS?
How Much RAM
How much disk space used, how much free?
What operations are slow?
Have you looked at Activity Monitor to see what the system is doing?
Have you tried logging out of this user and logging in as a Guest or test user? Does the performance change?
Have you tried doing a Safe Boot (shift key down), and choosing Shut Down when it gets to the login screen, and then restarting?
Have you looked at the Console Logs to see if anything strange is being reported?
As others mentioned, check SMART status with SMART Utility.
