初入SpringCloud坑的小白 把SpringCloud负载均衡作为毕设课题研究 能不能有个大佬帮我分析一下问题
三台服务器 学生云 1核2G 带宽1M 五个项目
Eureka，fegin消费者，clientA，clientB，clientC三个生产者
服务器1：Eureka，feign ，clinetA
服务器2：clientB
服务器3：clientC
使用jmeter测试500线程/S 持续3秒 共计1500线程 访问feign和clientA
测试1访问feign：异常率在33%左右 测试2访问clientA：异常率在28-33%左右 异常的基本上都是连接超时failed: Connection timed out: connect
在服务器1上抓包查看请求发现有的请求报了一些错
