Can you share the rest of your dump-flows output or your flow configuration (from inventory)? With proactive-flood-mode enabled there should be a flow installed for each openflow enabled port which forwards to all other openflow enabled ports on said device.
If your goal is performance testing I would suggest you use directly the openflowplugin project and generate your flows by hand or via external script. At this point the l2switch project exists mostly for education/introductory purposes and your results may not be truly indicative of a real OpenFlow deployment in which flood-mode would most definitely not be used.
