If I understood the original report correctly, they were complaining
mostly about index size, so a table without indexes certainly isn't
a real helpful comparison.  Still, this brings up an important point:
AFAICS the paper doesn't even mention which mysql storage engine they're
using.  So it's *really* hard to tell what we're comparing to.

No, certainly not.  See
