# Ingress Performance Test Report

## Test Background

Verify that the throughput of Ingress-nginx can increase linearly after horizontal scaling, and understand its performance metrics to help users manage resources effectively.

## Benchmark

This article is based on the installation of Ingress-Nginx in DCE 5.0, with all parameters set to default configuration and without enabling features such as keepalive.

### Physical Machine

| Name        | CPU                                       |  CPU  | MEM  | Interface    |
|:------------|:------------------------------------------|:------|:-----|:-------------|
| Node 1      | Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz |  56C  | 128G | 10G Mellanox |
| Node 2      | Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz |  56C  | 128G | 10G Mellanox |
| wrk Client  | Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz |  56C  | 128G | 10G Mellanox |

The following data is obtained from load testing on physical servers.

| Number of Ingress-nginx CPUs | (wrk) Requests/sec  |
| :----------------------: | :-----------------: |
|          1               |       3209.66       |
|          2               |       5709.07       |
|          4               |       9005.79       |
|          8               |       20696.19      |

### Virtual Machine

| Name        | CPU                                       |  CPU  | MEM  |
|:------------|:------------------------------------------|:------|:-----|
| Node 1      | Intel(R) Xeon(R) Gold 5118 CPU @ 2.30GHz  |  16C  | 16G  |
| Node 2      | Intel(R) Xeon(R) Gold 5118 CPU @ 2.30GHz  |  16C  | 16G  |
| wrk Client  | Intel(R) Xeon(R) CPU E5-2680 v4 @ 2.40GHz |  56C  | 128G |

The following data is obtained from load testing on virtual servers.

| Number of Ingress-nginx CPUs | (wrk) Requests/sec  |
| :----------------------: | :-----------------: |
|          1               |       3022.68       |
|          2               |       5556.20       |
|          4               |       8616.95       |
|          8               |       11006.89      |
