let me explain you this behavior with 7731 links. The scenario is a 3 kms link and I am performing zap for BW tests.
Test1: one zap from A to B, b_thrput=104.3mbps
Test2: two simultaneous zaps from A to B, b_thrput_zap1=103.2mbps and b_thrput_zap2=102.3mbps ... so, technically I'm having 205.5mbps ¿how is it explain?
Test3: one zap in one direction and the other one in the other direction, simultaneously. Well, this affects the first zap and I am getting around 75mbps per direction, in total, 150mbps what is also more than test one.
Any clue explaining this behavior?
Thanks in advanced.
