dperf is a network load tester for cloud

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 connections. It can give detailed statistics and find every packet loss.

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	1	200,000,000	36	39
4	4	400,000,000	40	41

#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
