+#  - Same destination IP
+#  - Fake source IPs for each flow (fixed based on thread number)
+#
+# Useful for scale testing on receiver, to see whether silo'ing flows
+# works and scales.  For optimal scalability (on receiver) each
+# separate-flow should not access shared variables/data. This script
+# helps magnify any of these scaling issues by overloading the receiver.
