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

#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
