网络参数是从googlepixel9开源的代码抄的，google给它的安卓手机用的网络参数，我认为比较适合现代的网络环境，我把rmem改成和wmem一样了，因为服务器上传和下载都很重要，需要双向高速数据传输
net.ipv4.tcp_slow_start_after_idle=0是针对代理设置的，代理不需要慢启动

net.ipv4.tcp_notsent_lowat=16384，naive作者推荐131072，我选择cloudflare推荐的16384
https://blog.cloudflare.com/http-2-prioritization-with-nginx
net.ipv4.tcp_ecn=1则是我用了bbrv3，支持ecn就试了下，对网速没什么影响而且从原理上能降低网络拥塞，外国的网站服务器也普遍开了ecn，用bbrv3的可以打开试试，需要本地设备也打开ecn
用bbrv1的不需要打开ecn
