dpdk-net benchmark

Benchmark for different kind of workload, and different setups.

Single Zone

Machines are located close to each other, in the same data center.

Http read scenario

DPDK server serves a http html page, and tokio test client try to make as much traffic as possible. See:

• dpdk-bench-server
• dpdk-bench-client

Driver: mlx5_core: Ethernet controller: Mellanox Technologies MT27800 Family [ConnectX-5 Virtual Function]

Azure Bench Result:

• Standard_D2s_v5: 2 cpu, 2 queue pair.
• Standard_D4s_v5: 4 cpu, 4 queue pair.
• Standard_D8s_v5: 8 cpu, 8 queue pair.

Note:

• In some vm queue is less than cpu, so the machine is not fully utilized by the current bench server, which creates 1 thread per queue and process http request on that thread. But the above vm sizes has 1 queue per cpu.
• The bench-test tokio client runs on Standard_D8s_v5 VM. Itself has perf bottle neck, and manifests in the Standard_D8s_v5 server tests. (TODO: use DPDK as the test client.)
