Actually, when you fire up emacs, it reads .emacs.elc, the 
byte-compiled version of your .emacs file (I think), so re-compiling 
the file after making changes is essential.

Probably forgot to mention it, but PSGMLX does automagically byte 
compiles any of its *own* files if you edit them, so you don't need 
to worry about compiling any changes you make to the default PSGMLX 
configuration.

The reasoning is that the code will execute faster because it's 
partially compiled.

The shortcut method is to use the menus (when in elisp mode):
Emacs-Lisp -> Byte-compile This File

Of course, 'M-x byte-compile-file' also does the trick.

There are other byte-compiling options that may make more sense for 
a given context. See the attached screenshot 
'emacs-byte-compiling.png' for a visual of the menu-based usage.
