Question

我正在我的应用程序的调查页面上运行负载测试。

对于200个用户，每秒1个，1个循环通过测试180用户，并且仍然有20个用户低于异常。

请帮我修复。

我们使用Jmeter版本 - 3.2和JDK - 8.2。我们已经在相应的文件中跟踪代码。

httpclient4.retrycount = 1，hc.parameters.file = hc.parameters 在user.properties文件中添加的代码和 hc.parameters文件中 http.connection.stalecheck $ Boolean = true

Answer 1

将所有HTTP请求采样器的“实现”更改为HttpClient4。最简单的方法是使用HTTP Request Defaults配置元素。
在位于JMeter安装的/ bin文件夹下的user.properties文件中添加以下属性：

httpclient4.retrycount = 1 hc.parameters.file = hc.parameters
将下一行添加到hc.parameters文件（相同位置，JMeter的/ bin文件夹）

http.connection.stalecheck $布尔=真
重新启动JMeter。

您的“连接重置”问题应该消失。

Answer 2

我问similar question还没有答案，但是有助于将这一行添加到jmeter.properties：

https.socket.protocols=TLSv1.2

解决我的问题的原因是增加加速期或创建一个新的DNS，而这个DNS没有通过阻止某些请求的cloudflare服务。
