mpl compiler performance

Hello,
I am a novice user of mpl and I am running into slow
compile times with intel c++.

I have some 5 class templates that are each instantiated
some 20 times or so. (2mns or so per translation unit).

I will reread Appendix C of Abrahams and Gurtovoy's "C++
Template metaprogramming".
Is there any how-to or guide that describes idioms to avoid
that I can read before I fire off specific questions to
the list?

Regards,
