Emacs terribly slow

[Maindoor]

Hi,
    I'm using emacs 23.0.91.1 and i load a few files using load-file
    in my .emacs file like session, hide-mode-line, uniquify, color-theme
    bs.el etc. but lately its become very very slow. Emacs it seems is
    panting and running out of breath when i open a file or when I browse
    around the file. Is there any way to optimize for speed ?

Regards,
Maindoor.
