Just to make sure, you are not using a network drive to build on, are you?  
For me, doing that in Windows NT (using NFS or clearcase MVFS network 
filesystems) makes builds run a factor of 10-50 slower, even though they are 
fast as ever under Linux or FreeBSD on the same physical box.  I chalk it up 
to poor network code in Microsoft OS.
