no its an old dual 900MHz pentium 3 machine, with SCSI disk so its not
normally that bad...

indeed, it only takes 10-15 seconds to do nothing on my toy (199
targets reported) test project... if I mirror some of the remote files
locally to give an unfair test against make it is nearer 1-2s.

make is near instant, even with remote files, but then that's NFS not
SMB, linux not windows, etc. and in make I have a cached set of
dependancies, that ignore system includes, which is what I tag Boost
as, my make projects only work for our Unix systems (IRIX and Linux),
not Windows which was one of the reasons I could spend some time on
trying BB.
