Hi,
I managed to solve this performance issue. I got improved performance after
turning off the mrg_rxbuf and increasing the rx and tx queue sizes to 1024.
Thanks,

Hi,
We figured out that the packet processing appliance within VM (which reads
from raw socket on the dpdk vhost user interface) requires more packets per
second to give higher throughput. Else its cpu utilization is idle most of
the times.
We increased the "tx-flush-interval" from default 0 to
Hi Tiago,
Sure. I'll try that.
Thanks,

Hi Onkar,
Thanks for shedding some light.
I don't think your difference in performance will have to do your
OvS-DPDK setup. If you're taking the measurements directly from the
iperf server side you'd be going through the "Internet". Assuming you
don't have a dedicated connection there, things

Hi Onkar,
Thanks for your email. Your setup isn't very clear to me, so a few
queries in-line.

Hi,
I have been experimenting with OVS DPDK on 1G interfaces. The system has 8
cores (hyperthreading enabled) mix of dpdk and non-dpdk capable ports, but
the data traffic runs only on dpdk ports.
DPDK ports are backed by vhost user netdev and I have configured the system
so that hugepages are
