   That's assuming you had to keep the whole repository in RAM.  While
you may have to do this with CVS, since you search so many of the files
from head to toe, that would be less common in the db4 respository that
subversion generates.  You might need to keep more bytes cached for good
performance, but I don't think you'd need as much of an increase as the
on-disk increase would suggest.
