Re: [boost] [msm] scalability
a library that I plan to submit to boost causes > 50 s compile times even for simple examples, so do you have any recommendations on where to start?
There is a template profiler from Steven Watanabe, you could start there: http://www.boost-consulting.com/vault/index.php?action=downloadfile&filename=profile_templates.zip&directory=Tools&
my library invokes a lot of Boost.Serialization and some MPL/fusion code, so I'm not even sure if I can do anything about that within my library.
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. HTH, Christophe

thanks. I get an empty output though, I think this might be related to a lot of errors I get in the intermediate output: (.rtp) ../../bin.v2/boost/persistence/gcc-4.3.2/debug/test.cpp:199: error: conflicting declaration ‘template_profiler_size’ this is caused by the fact that the preprocessor inserts the profiler also at namespace scope: namespace std __attribute__ ((__visibility__ ("default"))) { PROFILE_TRACER(); judging from the postprocessor, I don't think that is intended, is it? looks like it is only processing warnings. and the preprocessor also seems to only look for class and function headers. any idea how I could fix that?

The version there was rather out of date until about 2 minutes ago. It's also available in the sandbox http://svn.boost.org/svn/boost/sandbox/tools/profile_templates In Christ, Steven Watanabe
