I think it has been more than 6 months since typical database sizes
were below 80 MBytes.  As evidence, please consider

See the links in the first column of the private list of the
servers in the global network for other database sizes.

Installing a current version to replace the version 1.1.11 that you
are running would reduce the size of your database by 30-60%, because
the default lifetime of non-summarized reports of spam has been reduced
from 7 days to 1 day.

The slope of http://www.dcc-servers.net/dcc/graphs/db-size?resol=1year
for the last 3 months worries me, but I keep hoping it will flatten
eventually.  I hope the steep slope is due at least in part to the
<!--HTML comments--> noise that older versions of the checksums do
not ignore.
