JMeter本地压测Spring WebFlux WebClient遇连接拒绝及地址占用问题咨询

测试架构 #

/get       /process
JMeter -> Service 1 -> Service 2->| waits for
       <-           <-          <-| 300ms

JMeter调用Service 1的/get接口，该接口会进一步调用Service 2的/process接口。注：Service 1与Service 2共享同一代码库，仅调用不同接口。/process接口会等待500ms模拟业务处理，随后返回200状态码。

负载配置 #

使用JMeter配置约300个并发用户，逐步递增负载，测试总时长约5分钟。

测试报错信息 #

已尝试的解决方法 #

• 增加Tomcat最大线程数
• 修改Windows注册表中的MaxUserPort参数

疑问 #

当前负载配置是否超出本地环境承载能力？将服务和/或JMeter部署到独立机器是否更合适？
