Are you *normally* out to a CIFS shared location, or to local NTFS
disk? CIFS is very "chatty", and can often take 10 times as long to do
a checkout of a 1 Gig software working copy (in my personal
experience, 30 minutes instead of 3 for local disk).
Checkout to local disk, then copying it over to CIFS is grotesquely
faster. Maintaining a nightly updaed, checked out working copy for
copying to local working copies is also very effective to avoid this
slow down: the working copy can then be updated, far, far more
effectively.
