Dperf: 10M HTTP CPS Load tester

Dperf is a DPDK based high performance L4L7 load tester. It can also be a CPU benchmark for packets processing.

Main Features

• http/udp CPS(connections per second) test
• http/udp CC(current connections) test
• http/udp TPS(throughput per second) test
• multiple client/server network subnets
• multiple network interfaces
• ipv4/ipv6
• X86_64/ARM64
• dpdk versions: dpdk-17.11, dpdk-18.11, dpdk-19.11, dpdk-20.11

Performance

HTTP Connection per Second

Client Cores	Server Cores	HTTP CPS
1	1	2,101,044
2	2	4,000,423
4	4	7,010,743
6	6	10,027,172

HTTP Throughput per Second

Client Cores	Server Cores	RX(Gbps)	TX(Gbps))	Client CPU Usage(%)	Server CPU Usage(%)
1	1	18	18	60	59
2	2	35	35	60	59
4	4	46	46	43	43

HTTP Current Connections

Client Cores	Server Cores	Current Connections	Client CPU Usage(%)	Server CPU Usage(%)
1	1	100,000,000	34	39
2	1	200,000,000	36	39
4	4	400,000,000	40	41

Client & Server Configuration

• MEM: 512GB(hugepage 100GB)
• NIC: Mellanox MT27710 25Gbps * 2
• Kernel: 4.19.90

Getting Started

#set hugepages
#edit '/boot/grub2/grub.cfg' like this, and reboot the OS
#linux16 /vmlinuz-... nopku transparent_hugepage=never default_hugepagesz=1G hugepagesz=1G hugepages=8

#download & build dpdk
#download and unpack dpdk
TARGET=x86_64-native-linuxapp-gcc
#TARGET=arm64-armv8a-linuxapp-gcc
cd /root/dpdk/dpdk-stable-19.11.10
make install T=$TARGET -j16

#build dperf
cd dperf
make -j8 RTE_SDK=/root/dpdk/dpdk-stable-19.11.10 RTE_TARGET=$TARGET

#bind NIC
modprobe uio
insmod /root/dpdk/dpdk-stable-19.11.10/$TARGET/kmod/igb_uio.ko

#Suppose your PCI number is 0000:1b:00.0
/root/dpdk/dpdk-stable-19.11.10/usertools/dpdk-devbind.py -b igb_uio 0000:1b:00.0

#run dperf server
#dperf server bind at 6.6.241.27:80,  gateway is 6.6.241.1
./build/dperf -c test/http/server-cps.conf

#send request to dperf server at client
curl http://6.6.241.27/

Running the tests

Test HTTP CPS as shown below.

#run server at some host
./build/dperf -c test/http/server-cps.conf

#run client at another host
./build/dperf -c test/http/client-cps.conf
