You may be right.  I do not think these sizes match average object or
image on the Internet.  But usually what you are interested in is
simulating *your* traffic properties.

The numbers in the provided workloads should be a good starting point.
But for best results you should create distributions that match your
needs.  See [1] for details on user-defined distributions.  Creating
proper distributions for your tests may be difficult.  You will need
some existing data for it (e.g. Squid access logs).  Then you analyze it
with some auxiliary tools to get percentages for distributions (for
Squid access logs you might use access2pgl tool from
src/tools/access2poly/).
