GEOIP 解析时间很长

Surge Mac Version 3.3.3 (939)

查看 Dashboard 时经常能发现一些请求在解析 GEOIP 时花费了很长时间:

Surge 配置:

[General]
loglevel = notify
bypass-system = true
skip-proxy = 192.168.0.0/16, 10.0.0.0/8, 172.16.0.0/12, 127.0.0.1, localhost, *.local
bypass-tun = 192.168.0.0/16, 10.0.0.0/8, 172.16.0.0/12,127.0.0.0/24

hide-crashlytics-request = true
proxy-test-url = http://bing.com/
test-timeout = 5
dns-server = 223.5.5.5, system

[Rule]
DOMAIN-SUFFIX,youtube.com,Proxy
// ...
// 100 条左右的 DOMAIN-SUFFIX 规则
GEOIP,CN,DIRECT
FINAL,Proxy

试过在 GEOIP 这条后面加 no-resolve, 但这样的话国内的网站也都走 Proxy 了

geckofu 223.5.5.5 解析本来就慢，试试系统dns的解析速度，你会收获意外的惊喜

此耗时为 DNS 操作耗时，请检查 DNS 服务器连通性。

以上面的域名为例，我用 dig 测试的结果:

for ((i = 0; i < 1000; i++)); do 
  dig @223.5.5.5 community.nssurge.com | awk '/Query time:/{t=$4 " " msec}END{print t}'; 
done | jq -s max

56

向 223.5.5.5 查询了 1000 次 community.nssurge.com 的记录，耗时最久的一次是 56ms，和在 Dashboard 中记录的也相差了很多

community.nssurge.com 由于 DNS 服务器在境外，所以初次解析时间很长的话不奇怪，你再次访问 DNS 服务器就有缓存了，如果是 Dashboard 中偶尔出现某个域名 GEOIP 缓慢那么是正常的。

国内的域名也会遇到这样的情况，刚才试了豆瓣，微博，百度，简书，其中豆瓣和微博正常，百度和简书有比较大延迟：
