Hi Magnus,
Today I carried out some comparison tests between bpf-next and bpf-next +
xdp_multibuff series on mvneta running xdp_rxq_info sample. Results are
basically aligned:
bpf-next:
- xdp drop ~ 665Kpps
- xdp_tx ~ 291Kpps
- xdp_pass ~ 118Kpps
bpf-next + xdp_multibuff:
- xdp drop ~ 672Kpps
- xdp_tx ~ 288Kpps
- xdp_pass ~ 118Kpps
I am not sure if results are affected by the low power CPU, I will run some
tests on ixgbe card.
Regards,
Lorenzo
