Hey Allan,

First I would ensure you are running with your CPU in PERFORMANCE mode as follows:

for f in /sys/devices/system/cpu/cpu[0-9]*/cpufreq/scaling_governor ; do

  echo performance > $f

done

Second, you may want to not using a VM as this could cause unforeseen issues.

Hope this helps!

Regards,
Justin

Hi Andre,

I have a new PC with i7 and 6 cores dedicated to VM with Ubuntu running
Also installed the latest commit from git.

I am using a Samsung phone to connect to it.
I still see lot of L and U,
Attached the configs, logs and the pcap file.

What we are looking is areliableeNB with no disconnection from any tests.
Our tests would last 4-5 days in a stretch.

Any help will be great.

Regards,
Allan

Allen,

You're using 18.09 and it would be great if you could update to current
master on Github.

Also, from the logs it seems you have many lates and underflows, make
sure you are running at max CPU speed and have a good enough PC for the
bandwidth you're using.

Cheers
Andre
