Did you try precompiling header files?

My results are:

inclusion 2,6 s (-02+link) precompilation 1,45 s (-02+link) diff *1.8*

gcc 4.2, boost 1.41

There is one big issue with precompiled headers -- you only have one such header. So it is all or nothing, This is problematic, I tinkered a lot with PCH and various configurations. So far the best: - Use forward declarations - Include only that you need Gives much better performance then - Include everything in PCH - Include PCH everywhere. Artyom
