Iperf test

[MuhammadKhidr0164]

Hi All 

I am trying an Iperf3 test however it is in GNS3 but works fine for low BW testing but not for higher BW

while testing BW till 512 K it is ok and i can notice the transferred packet is about 64K but while increasing the BW to be tested i can notice that the packet is increasing and that affect the test 

any help with that ?

Kindly find the examples below

You're likely pushing your emulator platform beyond what it's capable of. I would imagine using a "faster" host platform would allow an increase in IPerf's capacity, or use it natively (i.e. not under GNS).
