分享一个测试路由器 连接数 的网站
在路由器中有一个重要负载，就是活动连接，在一些安装了OpenWrt系统的路由中，编译系统的作者可能会把值设置的很大，比如65536，给人感觉路由器上限变高了，能同时带六万多个连接。
牛不牛还得实测过才知道，分享一个测试网站
原理：通过随机生成子域名，在浏览器中疯狂发起请求，达成刷连接数的目的。
连接数会吃掉路由大量性能和内存，在内存不足，且没有合理限制连接数的情况下，可能会把其他的服务挤崩溃，如OpenClash。
个别光猫如果是软桥接的话，可能还会被光猫所限制，有的限制2000，超过光猫连接数会跳ping。
最后附带一下修改最大活动连接的方法，修改/etc/sysctl.d/11-nf-conntrack.conf
net.netfilter.nf_conntrack_max=65536
再备份一下网站源码，写的真不错~
需要自行导入jquery-2.1.3.min.js
