@daisyfloor tun 走 v4 了吧

@allplay 有 GPG 签名的

@hefish 据说得配置一下鉴权，被扫到也没事

理论上海外域名不应该解析，直接落地机器处理，速度会快很多。平时用阿里云那个 DoH 就行（不过也有被投毒的说法了）。

直接让 DoH 走代理得了，需要注意，最好是支持 EDNS 的，否则服务器境内境外解析不一样的解析到海外地址很蛋疼，不如直接代理了。Cloudflare 的不支持。

acme.sh 主要是重复签发，很多台机器都要来一遍好麻烦，功能性非常好了，算是事实上的标准之一？

不知道有没有开源的单机部署然后把证书文件推送到其他机器的方案，然后自动触发服务重载。

可以看看我的总结，和牢 B 的 PCDN 斗争久了经验还是有的

目前根据 bench 结果:

```

但是我的测试环境发生变动: AMD AI9 HX370, 7500MT LPDDR5.

fn bench_maps(c: &mut Criterion) {
let mut group = c.benchmark_group("Anyhow");

group.bench_function("anyhow/v1.0.76", |b| {

|e| {

});
},

});
}

criterion_group!(benches, bench_maps);
criterion_main!(benches);
```

切换至当前 stable rust 测试:

emmm, 奇怪的结果.

说白了要不是大小核谁升级 Windows 11, 用 Windows 不还是因为蛮多专业软件只有 Windows 版本, 游戏也是... 所以求稳才是第一.

卧槽, 分分钟被取消备案, 国内机器搭 DNS 是违法的我记得
