Hi All,
While sending 2G traffic of 64bytes size, I see a low performance for Phy-Phy
setup using OVS with DPDK. I get around 1500/1500 throughput.
Following are the Platform and setup details:
NOTE: Used OVS 2.4 and DPDK2.0.0
1. Intel(R) Atom(TM)
2. I assigned 1core to vswitchd process
3. Bound four I350 nics to igb_uio driver assume the ports namely 1,2,3,4.
4. Written the flow rules in such a way that the traffic flows from 1-2 and 3-4
5. Used DPDK Pktgen to pump 2G traffic of 64bytes size from port 1 and port 3.
I observed the following things:
1.Even though 2G traffic is pumped, the rate is still 1500/1500.
I am really not sure why each NIC is not transmitting beyond 750Mbps and
sometimes even less around 700Mbps.
2.I also see that the receive side error counters are incremented
in ovs-ofctl dump-ports br0 command.
Can you please let me know why the receive side error counters are incremented
and when does
these counters generally increment and also should I make any I350 NIC specific
changes
in the code to improve the performance?
Thanks in advance.
Regards,
Ravali.
