English | 中文

dperf is a DPDK based 100Gbps network performance and load testing software.

Advantage

High performance：
- Based on DPDK, dperf can generate huge traffic with a single x86 server: tens of millions of HTTP CPS，hundreds of Gbps throughput and billions of concurrent connections.
Detailed statistics：
- Provides detailed statistics and identify every packet loss.
Support multiple scenarios：
- Load testing and stability testing for Layer 4 Load Balancer and other Layer 4 gateways
- Network performance testing for servers on cloud
- Performance test of network package processing capability for NIC and CPU
- Can be used as a high performance HTTP server or client for load testing

Performance

HTTP Connections 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	2	200,000,000	36	39
4	4	400,000,000	40	41

UDP TX PPS

Client Cores	TX MPPS	Client CPU Usage(%)
1	15.96	95
2	29.95	95
4	34.92	67
6	35.92	54
8	37.12	22

Note: this test is under one 25Gbps Mellanox CX4

Client & Server Configuration

Above performance is obtained with below configurations:

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

Statistics

dperf outputs various statistics every second：

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

Build DPDK

#edit 'config/common_base' to enable PMDs
#Mellanox CX4/CX5 requires 'CONFIG_RTE_LIBRTE_MLX5_PMD=y'
#HNS3 requires 'CONFIG_RTE_LIBRTE_HNS3_PMD=y'
#VMXNET3 requires 'CONFIG_RTE_LIBRTE_VMXNET3_PMD=y'

TARGET=x86_64-native-linuxapp-gcc #or 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 interface

#Mellanox NIC skip this step!
#Suppose your PCI number is 0000:1b:00.0

modprobe uio
modprobe uio_pci_generic
/root/dpdk/dpdk-stable-19.11.10/usertools/dpdk-devbind.py -b uio_pci_generic 0000:1b:00.0

Start 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 from a client

#the client IP must be in the range of 'client' in the configuration file
ping 6.6.241.27
curl http://6.6.241.27/

Running the tests

Below example will start a HTTP CPS stress test. #run dperf server ./build/dperf -c test/http/server-cps.conf

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

Documentation

See the website at https://dperf.org/.

Limitation

dperf requires that the HTTP message is in one packet, which is not suitable for the test of layer 7 load balancer;
dperf requires exclusive use of the network interfaces.
dperf does not have routing capability. It is recommended to build a test environment with a switch.
