Hello
I did experiments where I sent packets to the hairpin queues and the CPU
queue at the same time.
During testing, I found that when the CPU queue is overloaded too much,
the hairpin queues also begin to drop packets.
Example 1:
Sending 10 Gbps to hairpin queues
Resulting throughput is 10
Hi Dmitry,
Thank you for your helpful reply.
Try enabling "Explicit Tx rule" mode if possible.
I was able to achieve 137 Mpps @ 64B with the following command:
dpdk-testpmd -a 21:00.0 -a c1:00.0 --in-memory -- \
-i --rxq=1 --txq=1 --hairpinq=8 --hairpin-mode=0x10
Based o this I was able
