btw - is there (like in linux) a vpp function helper "interface-name-to-if-index" - which its input is interface-name and output is vpp-if-index ? Thank you -Sara On Mon, Mar 12, 2018 at 5:16 PM, Sara Gittlin wrote: > Thank you Jon > This indeed very helpful ! >

Re: [vpp-dev] VPP As A Router Between Namespaces - 10ms latency

Could you try again with taps and large rings? create tap rx-ring-size 4096 tx-ring-size 4096 create tap rx-ring-size 4096 tx-ring-size 4096 Configure then the two taps in your namespaces and run iperf again. Hope this helps, Florin > On Mar 7, 2018, at 11:01 AM, Sara Gittlin

Thank you Hau i tested w iperf got similar results. I cannot find iperf2. Anyway ns to ns directly without vpp is perfect 50 gbps throughput and 10us latency. Tested w iperf3. This is very bothering since we decided to go w vpp instead of ovs Thanks in advance -Sara בתאריך 6 במרץ 2018 20:00,‏

Re: [vpp-dev] VPP As A Router Between Namespaces - 10ms latency

I encountered the similar issue before. Try replacing iperf3 with iperf2. Hao On 3/6/18, 8:34 AM, "vpp-dev@lists.fd.io on behalf of Sara Gittlin" wrote: Also the throughput is very poor - iperf3 TCP ~ 2Mbps what is wrong here ?

Hi, i have 2 namespaces connected with veth-pairs to vpp - see setup here [https://wiki.fd.io/view/VPP/Configure_VPP_As_A_Router_Between_Namespaces] i see very big latency ~10ms when i ping between the 2 namespaces i expected to see latency in the order of 10's us
