I have not done some stats, indeed. :-)

The build/download or rebuild/redownload is really faster (at least
for some R packages) than the graft part for some machines with
spinning disks.  Well, I have been enough annoyed for some packages on
that machine to end by systematically run the '--no-grafts' option for
all packages. :-/
