Dear all,
I am running VPP on a CPU with 2 sockets and 4 virtual cores. The startup
configuration is the following:
unix {
> interactive
> nodaemon
> }
>
> cpu {
> main-core 0
> corelist-workers 2-3
> *workers 2*
> }
>
> dpdk {
> dev 0000:07:00.0
{
> num-rx-queues 2
> }
> dev 0000:07:00.1
socket-mem 1024,1024
> }
The thread placement is the following:
> Thread 1 (vpp_wk_0 at lcore 2):
> *TenGigabitEthernet7/0/0 queue 0*
> TenGigabitEthernet7/0/1 queue 0
> Thread 2 (vpp_wk_1 at lcore 3):
> * TenGigabitEthernet7/0/0 queue 1*
So, I can see that RSS is working because the first queue of the first
interface is on lcore2 whereas the second queue is on lcore3.
I am running a simple L2-xconnect with the following command:
> set int l2 xconnect TenGigabitEthernet7/0/0 TenGigabitEthernet7/0/1
I am expecting the second thread actually working when the first cannot
handle all the traffic.
Therefore, I am saturating the RX bandwidth of TenGigabitEthernet7/0/0 sending
14 Mpps (packets of 64B).
I am receiving on TenGigabitEthernet7/0/1 only ~13Mpps which means that I
am not able to process ~ 1Mpps.
However, when I perform "show run", the second thread does not work at all!
Am I missing something in the configuration of VPP or what do you think can
be the cause?
Thanks for the help :)
Best regards,
Alessio
