Also, is there a way to prevent emacs native-comp to compile some 
packages, some kind
of blacklist. I would prefer at the moment because I am used to 
this color theme.

Do you think there may be a noticeable difference on emacs's 
performance between a
color theme natively compiled (*eln) or just byte compiled (*elc)

Regards
