[Boost-users] 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,
