各位大佬咨询一下,我使用webman在本地测试有24w的 QPS,但是在局域网测试的话就瞬间降低了3.6倍,网卡是万兆的网卡这问题会出现在什么地方?
压测机,和后台机器都有对内核进行优化

本地127.0.0.1不走网卡

  • 橘叔 2022-05-19

    谢谢大佬指点,我有疑问,万兆的网卡怎么会直接降低将近四倍的性能

  • 842461193 2022-05-19

    你走网卡就肯定有性能损耗啊,你ping下127.0.0.1和局域网ip看下延迟就知道了

压力机也是万兆网卡?

  • 橘叔 2022-05-19

    恩,两台都是万兆网卡

  • six 2022-05-19

    直接在本机用 http://192.168.3.26/ 压测下,如果还是差别这么大,就是走网卡导致的。如果出入不大,那可能是两台服务器间连接的路由器或者交换机问题,比如路由器或者交换机不是万兆出口的。还有网线可能不是万兆网线。

    我本机压测192.168.3.26更快...

    那可以考虑压力机自身是否有问题。还有路由器、交换机、网线这些是否支持万兆带宽这些问题。

这一看就是 路由器的问题,路由器处理不过来,买个5000块的华为交换机,肯定ok

    机房网络用的交换机都是几万大洋的
