Just running the globing of headers, on Win2K under MSYS run a few times 
to cache the filesys info:

grafik_at_KLUDGE /c/DevRoots/Boost/boost
$ date ; bjam > /dev/null ; date ; bjam --v2 > /dev/null ; date

Wed Jul 26 12:01:08 CDT 2006
Wed Jul 26 12:01:34 CDT 2006

So thats 4s for BBv1, and 26s for BBv2. Also I just noticed that the 
BBv2 code still misses some headers it should be copying that don't have 
  file extensions.
