dns 服务器性能

[holinhot]

双 Intel Xeon E5 2650 v2
192 GB 内存
3x 500 SSD RAID0

这样一台权威服务器powerdns每秒可以处理多少次dns查询请求

[acpp]

看程序员的编码能力。。

[holinhot]

@acpp powerdns不是现成的吗

[holinhot]

试了下linode 最便宜的配置

@acpp 额，不是根据硬件配置和网络带宽吗？

[holinhot]

@mrhuiyu 肯定也有关的

[acpp]

@holinhot 你是要自己做一个dns服务器哦吗？

[holinhot]

@acpp 肯定啊

[acpp]

@holinhot 现在网上那么多，你自己做来干啥用啊，

[Showfom]

Raid0 。。。。硬盘坏了你会哭的

[br00k]

感觉瓶颈主要在带宽。。。

[sdcg1994]

因为有递归服务器缓存的缘故。。其实各根域名服务器和域名权威解析服务器的请求量没你想象的那么多
http://k.root-servers.org/statistics/ROOT/ip_protocols.html
貌似K根服务器的请求量也只有5万/s 左右

[holinhot]

@sdcg1994 那个qps是用来应对查询攻击的吧。正常情况下哪会1秒10w次

[holinhot]

@Showfom 我会告诉你我每部署一个节点只要几分钟吗

[holinhot]

@acpp 网上那些管理太麻烦了 比如我要导入1w个域名 修改5000个解析记录那是非常痛苦的

受制于人当然不行啊

@holinhot 弄站群的？
