The boost libs(ver 1_34_1) have already been installed and built correctly. But i still find that the compile precess of each file of my project will become quite slow if a boost function call is included. The total time spending on the compilation of my project may exceed 20 minutes.  And I think that is quite long if compared with the compilation of a project with pure funcitons of VC libs.
 
Can anyone give me any advice on how to accelerate the compilation? Thanks ahead.

Are you using pre-compiled headers?

If not, each compilation unit (.cpp file) will be pulling in the complete include tree and recompiling it every time.
