# 压力测试报告（单机）

> WuKongIM 单机模式性能压力测试详细报告

## 前序

一个通讯系统是否优秀，主要看四个指标`高性能`,`稳定性`，`可靠性`，`有序性`。

**高性能**：极限压测消息发送并发和消息接收并发。

**稳定性**：测试在高并发下长时间运行，cpu，内存是否稳定

**可靠性**：测试是否丢消息。

**有序性**：测试消息是否乱序。

## 测试环境

所有的压测结果按照压测内容和硬件都能在自己服务器上复现。

**WuKongIM测试版本**：`v2.1.2-20250120`

**测试结果**

| 指标     | 值             |
| :----- | :------------ |
| 发送消息总数 | `2千万条`        |
| 发送消息并发 | `4万/秒`        |
| 发送平均延迟 | `400ms～600ms` |
| 内存占用   | `1～2G`        |
| CPU占用  | `60～80%`      |

**总结**：发送并发达到`4万/秒`的情况下，消息发送平均延迟还在毫秒内，内存稳定，CPU预期内，爆赞👍

（如果您对`4万/秒`没概念，拿mysql来说， 16核服务器下写入性能大概3000～8000/秒左右，`4万/秒`接近redis开启AOF模式下的写入性能）

**测试结果**

| 指标     | 值          |
| :----- | :--------- |
| 发送消息数  | `～400万条`   |
| 发送并发   | `1.2万条/秒`  |
| 发送平均延迟 | `10～500ms` |
| 接受消息数  | `～1000万条`  |
| 接受并发   | `3.6万条/秒`  |
| 接受平均延迟 | `1s以下`     |
| 内存占用   | `1～2G`     |
| CPU占用  | `70～80%`   |

**总结**：在压榨服务器的性能下，发送并发和接收并发分别达到了 `1.2w/s`和`3.6w/s` 表现非常优秀。

## 稳定性测试

测试系统是否能在消息低延迟下稳定运行

### 测试目标

测试在发送和接收并发高频的情况下，系统能够平稳运行，消息平均延迟在理想状态（500ms以下）。

## 有序性测试

测试消息是否乱序

### 测试目标

在一个频道内快速发送消息，看接收者的顺序是否与发送者的一致

### 测试内容

| 内容   | 在线   | 发送速率   |
| :--- | :--- | :----- |
| 1对单聊 | 2人在线 | 快速发送消息 |
