There is a template profiler from Steven Watanabe, you could start there:

As you use some MPL, you should check all your algorithms for
complexity (especially if you use many mpl::fold). A quadratic
complexity in a metaprogram will hurt you pretty fast.
I had the feeling that SFINAE also hurts you quite much on some compilers.
