介绍
本文将介绍如何使用Apache JMeter（JMeter）工具对Webman框架进行极限压测，以评估其性能。JMeter是一个广泛使用的开源负载测试工具，可用于模拟高并发请求并评估系统的响应能力。通过使用JMeter进行极限压测，我们可以深入了解Webman框架在高负载条件下的性能表现。
ECS 配置
代码语言：javascript复制2 vCPU 8 GiB （I/O优化）
ecs.g7.large 100Mbps （峰值）
压测场景
Windows 环境
在Windows环境下测试，并发数过大，整个主机直接崩掉.
Intel(R) Core(TM) i5-8400 CPU @ 2.80GHz 2.81 GHz64 位操作系统 24.0 GB
Linux 环境
依赖说明
在Linux系统中运行JMeter脚本，需要有两个前提：
- Linux系统中配置好Java环境
- Linux系统中配置好JMeter环境。（因为JMeter的运行需要Java环境）
环境说明
Java版本

脚本关键参数说明
- -n：表示non gui mode，就是非图形化模式。
- -t：指定JMX脚本路径，即test plan（测试计划）。后面跟需要运行的JMeter 脚本的路径和脚本名称。
- -l：指定结果文件路径。后面跟输出结果文件路径和结果文件名称。-e：设置测试完成后生成测试报表。-e：设置测试完成后生成测试报表。-m：设置测试完成后生成测试报表。
- 1）若没有指定指定结果文件路径，则自动创建，可以生成.csv文件或者.jtl文件。
- 2）若只写脚本名称，则默认是在当前目录查找或创建。
- -e：设置测试完成后生成测试报表。
- -o：指定测试报表生成文件夹。文件夹必须为空或不存在。

总结
负载均衡SLB测试
「单机QPS：3000左右」
单机测试
移除负载均衡SLB（由于https证书太垃圾了，导致证书验证老是超时问题）
「QPS最大是：28000」（server数：16个）
