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?

    provide all above statistics for A and B at this point (where drop 

One thing I missed in your original post what protocol drops packet --
