Could anyone explain the basic difference between these two functions? Sage's documentation says that find_local_minimum uses fminbound, so... what find_local_minimum does?

Also, is there a performance difference between them?

Check the documentation:

sage: import scipy.optimize
sage: scipy.optimize.fminbound?

Check the source code:
