Thanks Keith. Let me post my questions again and inline the text.
--------------------------------------------------------------------------------------------------------------- Hi developers, Below is my hardware configuration: Memory: 32G ( 16 G on two channels ) CPU: Xeon-D 1557 NIC: Intel X552/X557 10GBASE-T CPU layout: ( Graph generated from cpu_layout.py ) Core and Socket Information (as reported by '/proc/cpuinfo') ============================================================ *cores = [0, 1, 2, 3, 4, 5, 8, 9, 10, 11, 12, 13]sockets = [0] Socket 0 -------- Core 0 [0, 12] Core 1 [1, 13] Core 2 [2, 14] Core 3 [3, 15] Core 4 [4, 16] Core 5 [5, 17] Core 8 [6, 18] Core 9 [7, 19] Core 10 [8, 20] Core 11 [9, 21] Core 12 [10, 22] Core 13 [11, 23]* ============================================================= My motherboard has 2 10G ports so that I set up the testing experiment in loopback. I have compiled DPDK successfully and below is the steps how I configured pktgen $ sudo modprobe uio $ sudo insmod ./build/kmod/igb_uio.ko $ sudo ./usertools/dpdkdevbind.py -b igb_uio xxx:xx.0 xxx:xx.1 $ sudo ./app/pktgen -c 0x1f -n 2 -- -P -m "[1:3].0, [2:4].1" <pktgen> start 0 I use core 1 and core 3 work for port 0 tx/rx respectively. Core 2 and core 4 work for port 1 tx/rx respectively. I have some questions listed below: 1. I checked other developers who run pktgen successfully should get the TX/RX rate almost the same and the value should hit 10000 or 99xx. I have not figured out yet why the rate went down when I run pktgen. * Flags:Port : P--------------:0 P--------------:1 10318718/0Link State : <UP-10000-FD> <UP-10000-FD> ----TotalRate----Pkts/s Max/Rx : 0/0 10318848/8096382 10318848/8096382 Max/Tx : 14880683/11528400 0/0 14880683/11528400MBits/s Rx/Tx : 0/7747 5440/0 5440/7747Broadcast : 0 0Multicast : 0 0 64 Bytes : 0 4603033247 65-127 : 0 0 128-255 : 0 0 256-511 : 0 0 512-1023 : 0 0 1024-1518 : 0 0Runts/Jumbos : 0/0 0/0Errors Rx/Tx : 0/0 0/0Total Rx Pkts : 0 4596736394 Tx Pkts : 6588970508 0 Rx MBs : 0 3089006 Tx MBs : 4427788 0ARP/ICMP Pkts : 0/0 0/0Tx Count/% Rate : Forever /100% Forever /100%Pattern Type : abcd... abcd...Tx Count/% Rate : Forever /100% Forever /100%PktSize/Tx Burst : 64 / 32 64 / 32 -------------------Src/Dest Port : 1234 / 5678 1234 / 5678sPkt Type:VLAN ID : IPv4 / TCP:0001 IPv4 / TCP:0001Dst IP Address : 192.168.1.1 192.168.0.1Src IP Address : 192.168.0.1/24 <http://192.168.0.1/24> 192.168.1.1/24 <http://192.168.1.1/24> -------------------Dst MAC Address : 0c:c4:7a:c5:43:7b 0c:c4:7a:c5:43:7a-- Pktgen Ver: 3.3: 8086:15ad/03:00.0 8086:15ad/03:00.1 -------------------* 2.1 My start_log below: Copyright (c) <2010-2017>, Intel Corporation.
