Its not so bad. At least its linear: 

TAR
              Total Size  Revisions   Total Size / revisions
Archive:      17MB        1379        12.3KB
Project Tree: 7.7MB       1379        5.6KB

AUTOMAKE

              Total Size  Revisions   Total Size / revisions
Archive:                  3363        
Project Tree:  25MB       3363        7.4KB


I'll throw a wild guess that you ended up with an
{archives} size of around.... oh say 40 megabytes.


Also, one very big point to make here. This problem can be solved by
collapsing patches. If your team does 1000 patches a year and you have a
12:1 devo:mainline ratio, then the problem doesn't look *nearly* so bad.

It gets even worse if you use explicit tagging instead of tagline/names
based tagging, because of all of those .arch-ids.
