Hi,
I want to check the performance of DPDK OVS in aspect of forwarding as below URL. https://drive.google.com/a/os.korea.ac.kr/file/d/ 0BxEx0xE0gw2ETjhkaUpzN3YxSVU/view?usp=sharing There is a similar experiment at 'IntelĀ® Open Network Platform Release 2.1 Performance Test Report'. Also, there is the result of this. the result shows that when DPDK OVS use multi poll-mode thread and receive multi flows packet, it can achieve amazing throughput. Thus, it can achieves high performance in multi-flows environment. However, I couldn't make this result in my experiment environment. when I made 10 types of packet by DPDK pktgen machine, the throughput dropped by 2Gbps. with single flow and multi threading, the throughput is 8Gbps in my machine. Thus, it is a big problem to me. What makes these the problems in my experiment? Please Help me. My setting is as below: Hardware(both is same) - cpu: Xeon 2630 v2 *2 (NUMA) - mem: 48G (sum of hugepage(1G) :16G) - nic: 82599 ES Software(DPDK OVS) - OS: ubuntu 16.04 - kernel 4.8.0-54 generic(default kernel) - DPDK :2.2 OVS :2.5.2 [I installed this from ubuntu package(ex. apt-get install ovs-vswitch-dpdk)] - the way to set flow table : "i=0 j=1 while [ $i != 1 ] do while [ $j != 255 ] do ovs-ofctl add-flow br0 ip,nw_dst=192.0."$i"."$j", actions=mod_dl_dst:90:e2:ba:5b:88:2c,in_port j=$((j+1)) done j=1 i=$((i+1)) done" - used commands for multi queues & threads: ovs-vsctl set Open_vSwitch . other_config:pmd-cpu-mask=0x3f ovs-vsctl set Open_vSwitch . other_config:n-dpdk-rxqs=4 ovs-vsctl set Open_vSwitch . other_config:n-dpdk-txqs=4 Software(Pktgen) - multi flow command (lua): pktgen.dst_mac("all","start","90:e2:ba:5a:78:30"); pktgen.dst_mac("all","inc","00:00:00:00:00:00"); pktgen.dst_mac("all","min","90:e2:ba:5a:78:30"); pktgen.dst_mac("all","max","90:e2:ba:5a:78:30"); pktgen.src_mac("all","start","90:e2:ba:5b:88:2c"); pktgen.src_mac("all","inc","00:00:00:00:00:00"); pktgen.src_mac("all","min","90:e2:ba:5b:88:2c"); pktgen.src_mac("all","max","90:e2:ba:5b:88:2c"); --pktgen.delay(1000); pktgen.dst_ip("all","start","192.0.0.1"); pktgen.dst_ip("all","inc","0.0.0.1"); pktgen.dst_ip("all","min","192.0.0.1"); pktgen.dst_ip("all","max","192.0.0.10"); --pktgen.delay(1000); pktgen.src_ip("all","start","10.0.0.1"); pktgen.src_ip("all","inc","0.0.0.0"); pktgen.src_ip("all","min","10.0.0.1"); pktgen.src_ip("all","max","10.0.0.1"); --pktgen.delay(1000); pktgen.src_port("all","start",9); pktgen.src_port("all","inc",0); pktgen.src_port("all","min",9); pktgen.src_port("all","max",9); --pktgen.delay(1000); pktgen.dst_port("all","start",10); pktgen.dst_port("all","inc",0); pktgen.dst_port("all","min",10); pktgen.dst_port("all","max",10); --pktgen.delay(1000); pktgen.pkt_size("all","start",64); pktgen.pkt_size("all","inc",0); pktgen.pkt_size("all","min",64); pktgen.pkt_size("all","max",64); pktgen.set_proto("all","tcp"); pktgen.set_type("all","ipv4"); - Use 10 core ./app/app/x86_64-native-linuxapp-gcc/pktgen -c 0x7df -n 4 -- -f multiflow.lua -N -m "[1-5:6-10].0" Please let me know if you have any insights.
