Subject: [dpdk-users] Any way to get more that 40Mpps with 64bytes using a XL710 40Gb nic
Date: Thu, 28 Sep 2017 11:06:58 +0000 [thread overview]
Message-ID: <AD12A428-1D05-4E8F-A198-403E1805F883@contoso.com> (raw)
Hi Guys;
I am testing a Fortville 40Gb nic with PKTgen
I see linerate in 40Gb with 156B packet size, but once I decrease size, linerate is far away
WITH 158B
Link State : <UP-40000-FD> ----TotalRate----
Pkts/s Max/Rx : 0/0 0/0
Max/Tx : 28090480/28089840 28090480/28089840
MBits/s Rx/Tx : 0/40000 0/40000
-----------------------------------------------------------------------------------------------
WITH 128B
Link State : <UP-40000-FD> ----TotalRate----
Pkts/s Max/Rx : 0/0 0/0
Max/Tx : 33784179/33783908 33784179/33783908
MBits/s Rx/Tx : 0/40000 0/40000
------------------------------------------------------------------------------------------------
With 64B
Link State : <UP-40000-FD> ----TotalRate----
Pkts/s Max/Rx : 0/0 0/0
Max/Tx : 35944587/35941680 35944587/35941680
MBits/s Rx/Tx : 0/24152 0/24152
----------------------------------------------------------------------------------------------
Should I run any optimization?
My environment is:
•VMware ESXi version: 6.5.0, 4887370
•Exact NIC version: Intel Corporation XL710 for 40GbE QSFP+
•NIC driver version: i40en version 1.3.1
•Server Vendor: Dell
•Server Make: Dell Inc. PowerEdge R730
•CPU Model: I ntel(R) Xeon(R) CPU E5-2697 v3 @ 2.60GHz
•Huge pages size: 2M
•Test VM: What is it? Ubuntu 16.04
• DPDK is compiled there? dpdk-17.08
•Test traffic kind: IP/UDP? Both tested
Traffic generator: Intel pktgen version? pktgen-3.4.1
I am executing:
sudo ./app/x86_64-native-linuxapp-gcc/pktgen -c 0xff n 3 --proc-type auto --socket-mem 9096 -- -m "[1:2-7].0" --crc-strip
Thanks in advance
