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?
