Looks like you really have a good server there!
So this means that the problem is not RAM size either. Only remaining
is the pure size issue. Tony maintains that big files are not a
problem since only the deltas are stored and CVSNT can quickly access
HEAD at least.

But I understand your problem now and it is similar to the slightly
less problem we have with embedded microcontroller development. The
final result of a compile is a text file that is really the image of a
binary program in hex format. So it too changes almost completely
between rounds. We decided not to store this file in CVS because it
can be exactly created off of the stored sources (we did some tests
and the result was a 100% binary compare).
In your case, if you want to still save the file in CVS I would make a
cut somewhere and make a copy of the RCS file under another name and
then start anew by using the admin command and delete the first 17
revisions from the file. The renamed copy will serve as backup. Then
at least you can continue a while with a faster module...
