I would create my own content definitions. You can start with those in
contents.pg, but I strongly recommend to not modify any files in the
workload directory directly. Create my-contents.pg or similar instead.

Look at how PolyMix-4 uses different percentages (number of objects)
for different content types. See Server.contents in polymix-4-guts.pg.
Each content type can have any size distribution, including constant
and user-specified.
