Question

我正在通过HTTPS在Web应用程序上进行负载测试，并且在同时扩展60个以上的线程时遇到这些错误：

我正在使用Jmeter 5.1.1，并设置了httpclient.reset_state_on_thread_group_iteration=false。这些错误是否代表现实世界中可能发生的情况？如果是这样，解决这些问题的关键是什么？如果没有，我该如何修复我的Jmeter？

我试图在同时运行200个线程的同时访问该应用程序，并在同一台计算机上的Chrome中获得了ERR_CONNECTION_RESET。在另一台计算机，不同的网络上，我可以在负载测试期间访问该网站。所以瓶颈在我自己的测试机上

Answer 1

出现此错误时，请尝试手动访问应用程序。如果无法访问应用程序，则应用程序存在一些性能问题。但是，如果您可以轻松访问应用程序，则执行负载测试的方式会存在一些问题。

一个原因可能是执行Jmeter脚本的计算机的带宽较低。例如，如果您使用2Mbps线路，则所有Jmeter用户都只能共享该带宽，该带宽肯定很低（对于每个用户= 2Mbps / 60）。

Answer 2

该问题与后端无关，而与企业代理（鱿鱼）有关，因为我是从公司网络内部启动测试的，而目标是在Internet上。我已经为JMeter切换到公共云上的虚拟机，它解决了问题。

使用HTTPS时在Jmeter 5上重置连接
