Hello,

My DUT is a vrouter in a uCPE.

For stateless UDP traffic I can get to 900 Mbps without drops, while for stateful traffics like HTTP I barely get 110 Mbps (Max Rx).

Do you have any idea why such low Rx for stateful traffic ?

Thanks

Try TRex in loopback, ASTF consume much more resource

Thanks Hanoh,
My traffic passes through a vrouter inside a uCPE and comes back to TRex, and I want to test it with stateful traffic, The CPU utilization gets to 100% at 100Mbps, but I'd like to know why this difference between stateless and stateful, knowing that I only have a simple vrouter inside the uCPE.

I find it weird how the CPU utilization goes from 26% to 100% almost direcly, do you have any idea ?
Thanks !!
