Please Mention the hardware requirements .

Hi,
I am running DEMU with delay and jitter but not getting any expected result.
I am running iperf3 app to test bandwidth, jitter and packets loss on UDP

1. When run DEMU with 5000 us delay and 100 jitter
   `Demu server output
   

Iperf3 output :

2. When Delay - 50000 & jitter 1000

Demu console :

iperf3 output :

Please share your suggestion on following point :

1. There is any other application where we can test delay, jitter & bandwidth with DEMU
2. How can be enable logs of DEMU Server or log file

packet are lossing while we are not using "packet loss rate(r)"'
As i checked the code, there is mentioned that if we didn't use "packet loss rate(r)" then by default its value is "0" means there should not be data loss but we are getting data loss when we are executing following command

packet are lossing while we are not using "packet loss rate(r)"'
sudo /home/user/demu/demu/build/demu -c fc -n 4 -- -p 3

There is any other configuration required to run demu without packet loss.

Dear author
We have deploy Demu on one server and connect it with other two servers (serve as sender and receiver) to evaluate long RTT scenario. However, when we run perftest at the sender and run ib_write_bw, the perftest fails.
Here are the result:


So, what is the problem? Does Demu modify pakcets?
