| ### 测试环境 |
| |
| 使用谷歌云的服务器进行测试，型号为 n1-highcpu-8 (8 vCPUs, 7.2 GB memory) |
| |
| 我们最多只使用 4 核去运行 APISIX，剩下的 4 核用于系统和压力测试工具 [wrk](https://github.com/wg/wrk)。 |
| |
| ### 测试反向代理 |
| |
| 我们把 APISIX 当做反向代理来使用，不开启任何插件，响应体的大小为 1KB。 |
| |
| #### QPS |
| |
| 下图中 x 轴为 CPU 的使用个数，y 轴为每秒处理的请求数： |
| |
|  |
| |
| #### 延时 |
| |
| 请注意 y 轴延时的单位是**微秒（μs）**，而不是毫秒： |
| |
|  |
| |
| #### 火焰图 |
| |
| 火焰图的采样结果： |
| |
|  |
| |
| 如果你需要在本地服务器上运行基准测试，你需要同时运行另一个 NGINX 实例来监听 80 端口： |
| |
| :::note |
| |
| 您可以这样从 `config.yaml` 中获取 `admin_key` 并存入环境变量： |
| |
| ```bash |
| admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g') |
| ``` |
| |
| ::: |
| |
| ```bash |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "methods": ["GET"], |
| "uri": "/hello", |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "127.0.0.1:80": 1, |
| "127.0.0.2:80": 1 |
| } |
| } |
| }' |
| ``` |
| |
| 在完成配置并安装 [wrk](https://github.com/wg/wrk/) 之后，可以使用以下命令进行测试： |
| |
| ```bash |
| wrk -d 60 --latency http://127.0.0.1:9080/hello |
| ``` |
| |
| ### 测试反向代理，开启 2 个插件 |
| |
| 我们把 APISIX 当做反向代理来使用，开启限速和 prometheus 插件，响应体的大小为 1KB。 |
| |
| #### QPS |
| |
| 下图中 x 轴为 CPU 的使用个数，y 轴为每秒处理的请求数： |

| #### Latency |

| "uri": "/hello", |
| "plugins": { |
| "limit-count": { |
| "count": 999999999, |
| "time_window": 60, |
| "rejected_code": 503, |
| "key": "remote_addr" |
| }, |
| "prometheus":{} |
| }, |

| wrk -d 60 --latency http://127.0.0.1:9080/hello |
| ``` |

| 有关如何运行基准测试的更多参考，你可以查看此[PR](https://github.com/apache/apisix/pull/6136)和此[脚本](https://gist.github.com/membphis/137db97a4bf64d3653aa42f3e016bd01)。 |

| :::tip |
| |
| 如果您想使用大量连接运行基准测试，您可能需要更新 [**keepalive**](https://github.com/apache/apisix/blob/master/conf/config.yaml.example#L241) 配置，将配置添加到 [`config.yaml`](https://github.com/apache/apisix/blob/master/conf/config.yaml) 并重新加载 APISIX。否则超过配置数量的连接将成为短连接。你可以使用以下命令运行大量连接的基准测试： |
| |
| ```bash |
| wrk -t200 -c5000 -d30s http://127.0.0.1:9080/hello |
| ``` |
