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.
| Client Cores | Server Cores | HTTP CPS |
|---|---|---|
| 1 | 1 | 2,101,044 |
| 2 | 2 | 4,000,423 |
| 4 | 4 | 7,010,743 |

| Client Cores | Server Cores | RX(Gbps) | TX(Gbps)) | Client CPU Usage(%) | Server CPU Usage(%) |
