# Script will generate one flow per thread (-t N)

#  - 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.
