It's not recompilation speed, it's startup time.

It takes 7 seconds to initialize BJam on project with included Boost 
libraries on my notebook. MSVS takes less than a second.

The slowest part is timestamp checking (NTFS is sloooooow). I have an 
idea how to speed up this process, and I'll try to implement it in my 
upcoming BJamC++ (and backport to BJam if it is possible).

My idea is to use NTFS "Change Journal" 
(http://www.microsoft.com/msj/0999/journal/journal.aspx) to track file 
modifications combined with BJam's dependency caching.

Well, I have a simple script which creates .vcproj file from a directory 
tree :)
