Generic Lisp: Compilation and Evaluation

In Emacs + Slime with sbcl, as soon as I define a function (or more) in a file, I have two options:

  • Rating . with CMx eval-defun
  • Compilation . with compiler Cc Mk file

The second also creates the .fasl file.

What are the differences between the two?

What happens under the hood when compiling a definition / file?

What are the advantages and disadvantages of each?
