问题：
- 我asp.net在我的服务器（使用IIS）中测试我的www.example.com webapi应用程序，并发数设置为2000，循环计数是永久的，改变几秒后，我得到
Connection timed out: connect错误
我所尝试的：
1.在jmeter GUI中设置http连接超时和响应超时为200000ms。
1.在IIS管理器中将requestQueueLimit设置为65535，将最小进程数设置为15。
1.在web.config文件中将minWorkerThread和minIoThread设置为200，并将超时设置为20分钟，然后在IIS中重新启动我应用程序
以上都不起作用，我发现服务器的cpu使用率一直很低，下面是使用jmeter测试时的屏幕截图：

以下是错误日志：

1.在您的网站配置中选中
Maximum Concurrent Connections和other limits：高级设置-〉限制-〉最大并发连接数1.它可能根本没有与IIS连接，并且由于数据库配置不正确或使用了inefficient algorithms，可能会在您的网站级别发生超时。请考虑使用YourKit或dotTrace等分析工具遥测重新运行您的测试-它将为您提供有关引擎盖下发生的情况的完整信息
1.不要使用JMeter GUI运行负载测试，它只用于测试开发和调试，当涉及到执行时，您应该running your JMeter tests in command-line non-GUI mode
1.删除所有监听器，它们不会增加任何价值，只会消耗宝贵的资源
