I’m using a
I have a
DPDK application on which I want to support jumbo packets.
To do that I add rx offload capabilities:
And tx offload capabilities:
I also make the
max_rx_pkt_len higher so it will accept jumbo packets (9k).
I’ve noticed that adding these offload capabilities + increasing the
max_rx_pkt_len harms performance.
For example, without those offload flags, I can redirect 80Gbps packets of size 512 without any drop.
Using those flags reduce to ~55Gbps without losses.
Currently in this test I do not send jumbo packets. I just want to understand how it affects the average packet size.
Is this expected? Using those offload flags should degrade performance?
