[ashutoshharry]

Hi @yipingwang

we have 2 1088ARDB-PB connected back-to-back like WAN to WAN connected with 10G interface as WAN interface 

and we are tesing 10G speed optical but below is max speed we can achive 

TCP we are geting up to 9Gbs that good

but for UDP we are not geting more then 2.3Gbs 

we are testing using ipef client/server as testing.

please help

 For UDP iperf test, you need to specify bandwidth with option "-b".

Sever: iperf -s -u

Client: iperf -c 100.1.1.99 -P 10 -t 30 -u -b 10G

Please compile Linux Kernel with CONFIG_NETFILTER and CONFIG_CPU_FREQ disabled
