In a single x86 server, dperf can achieve:

• Tens of millions of new connections per second (CPS)
• Hundreds of millions of packets per second (PPS)
• Billions of concurrent connections (CC)
• Hundreds of gigabits per second of throughput (Gbps)

It supports HTTP, TCP, UDP, IPV4, IPV6, VLAN, VXLAN. It is great for testing layer 4 load balancers and network interfaces.

Supported platforms

• CPU: X86-64, ARM64, LoongArch.
• OS: Linux.
• NIC: DPDK Supported NICs.
• DPDK versions: 17, 18, 19, 20, 21, 22, 23, 24, 25.
