本文主要是介绍web api性能测试使用wrk，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！
web api性能测试
这边简单的给出shell脚本
注意先安装：wrk和gnuplot

API 性能测试脚本，会自动执行 wrk 命令，采集数据、分析数据并调用 gnuplot 画图使用方式 ( 测试 API 性能)：
1. 启动 iam-apiserver(8080端口)
2. 执行测试脚本: ./wrktest.sh脚本会生成 .dat 的数据文件，每列含义为：并发数 QPS 平均响应时间 成功率使用方式 (对比2次测试结果)
1. 性能测试：./wrktest.sh iam-apiserver http://127.0.0.1:8080/healthz
2. 执行命令： ./wrktest.sh diff apiserver.dat http.dat> Note: 需要确保系统安装了 wrk 和 gnuplot 工具

直接使用wrk命令
wrk -t144 -c3000 -d30s -T30s --latency 你的url
