Assume that you have process A to cause process B dropping packets:
Step (1):
Run B only -- what is the maximum through without packet drop?
what is the CPU utilization?
what type of traffic (protocol -- TCP, UDP, etc.)
does B use?
does B have other I/O? If so, how much is the I/O
bandwidth used?
Step (2):
reRun B and involving A gradually (increasing A's wieght) till B drops
packets.
provide all above statistics for A and B at this point (where drop
starts).
One thing I missed in your original post what protocol drops packet --
TCP or UDP?
