How much time speedup do you see?

Umm. Not really. There should be multiple translation units. 
BOOST_TEST_MAIN/BOOST_TEST_MODULE should be defined in only one of them. 
      This way you should be able to speedup compilation even more.

There is one - example #10

I believe there are couple in docs.
