Shadowsocks 各加密方式的速度测试报告

Shadowsocks 各加密方式的速度测试报告

TL;DR (仅针对当前版本)

  • 若不知道 CPU 是否支持 AES-NI, 则 chacha20-ietf-poly1305 为最稳妥的选择。
  • 若 CPU 支持 AES-NI, 则 shadowsocks-rust 选择 aes-128-gcm, shadowsocks-libev 选择 aes-256-gcm 为最佳。

记录一下 ChinaDNS 的工作原理和一些 DNS 相关的想法

ChinaDNS 的工作流程

ChinaDNS 的上游 DNS 分为 国内 DNS 和 可信 DNS。

工作流程

  1. ChinaDNS 会同时向上游的 DNS 发送请求。
  2. 如果 可信 DNS 先返回，则直接采用 可信 DNS 的结果。
  3. 如果 国内 DNS 先返回，分两种情况：如果返回的结果是国内的 IP, 则采用；否则丢弃并转而采用 可信 DNS 的结果。
