TIME_WAIT 其实是正常现象,再压测http接口都是都是短连接,每次建立连接的时候都会出现 TIME_WAIT,除非压测的时候建立长链接,只压测数据

@link1st 谢谢。还有一个这样的问题。
connect: cannot assign requested address

如下图,第一秒的时候并发数是4,是代表在第一秒中的时候 只有四个并发么。如果是这样的话,那QPS却是4W多。不知道这些数据怎么算出来的。

问题一:
connect: cannot assign requested address
无法分配请求地址,因为在TCP 连接的时候client需要占用一个端口,但是本地的端口是有限的,所以会出现无法分配端口的现象
解决:
设置更多的可用端口、修改地址快速回收
问题二:
QPS: 指的是一秒钟请求接口次数,这里平均耗时为 0.02 毫秒
QPS=1s*1000/0.02 等于50000,显示 0.02 毫秒因为小数舍去了,所以是40213.41
