jzperf is a L3-L7 network load tester.
- High performance:
- Based on DPDK, jzperf 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

Note: this test is under one 25Gbps Mellanox CX4
Above performance is obtained with below configurations:
- MEM: 512GB(hugepage 100GB)
- NIC: Mellanox MT27710 25Gbps * 2
- Kernel: 4.19.90
jzperf outputs various statistics every second:
- TPS, CPS, various PPS
- Errors of TCP/Socket/HTTP
- Packets loss/drop
- Retransmissions of TCP Flags
