dperf is a DPDK based 100Gbps network performance and load testing software.
- 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
| 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 |
| 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 |
| 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 |
Above performance is obtained with below configurations:
- MEM: 512GB(hugepage 100GB)
- NIC: Mellanox MT27710 25Gbps * 2
- Kernel: 4.19.90
dperf outputs various statistics every second：
- TPS, CPS, various PPS
- Errors of TCP/Socket/HTTP
- Packets loss/drop
- Retransmissions of TCP Flags

#verify if dperf is installed successfully
#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 to dperf server from a client
curl http://6.6.241.27/
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
- 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 uses the FDIR feature. For the network interface that do not have this feature, dperf can only run in 'single-threaded' mode.
- dperf does not have routing capability. It is recommended to build a test environment with a switch.
dperf welcomes your contribution. See the CONTRIBUTING file for details.
