In priority order, from what others said, and one addition (underlined)
How Much RAM
How much disk space used, how much free?
See what items are set to automatically start when the user logs in, in Accounts.
Have you tried logging out of this user and logging in as a Guest or test user? Does the performance change?
Run adware medic (google it) to clear up any hidden malware.
AFTER you've checked the backup to make sure it's perfect, you could try nuking and paving and reinstalling from backup, but that's a very last resort.
I'm betting on low RAM, or too little free disk space, or something running automatically in background......
