关于 V2EX 的访问速度

[Livid]

现在 www.v2ex.com 这个域名跑在一个高科技上，大家感觉和 v2ex.appspot.com 相比速度如何呢？

[majunbo]

不对，
www.v2ex.com 这个域名在qiang内比较快，
已经基本和qiang外的v2ex.appspot.com速度相当。
不错。

@yoyicue http://www.xgslb.net/html/wl011.html WebLuker SeeC服务（MiniCDN服务）提供所有CDN服务基本功能，通过智能的流量调度，将用户的访问解析到就近节点上，提高用户的访问质量

[fish]

直观感觉差不多

[AJ]

感覺上兩者差不多，但v2ex.appspot.com是用SSH上的，v2ex.com是直接上的

[dismory]

北京联通

ping www.v2ex.com 超时
ping v2ex.com 230ms

另, Win下刷新dns缓存的命令是 ipconfig /flushdns

[gonbo]

CDN 是吧，发贴还是会快不了，

动态内容也快不了。

不要迷信。


哈哈

从Ping的结果来看，v2ex.com要比appspot快

但是从打开页面的速度来看， 明显感觉appspot要更快一些

上面是appspot，下面是v2ex.com
用Chrome Developer Tools同时访问首页得出的简单对比

实际感受也是v2ex.com比较慢
广东电信4M ADSL

[lianghai]

印度新德里 Airtel：
v2ex.com 308–309ms
www.v2ex.com 450–460ms
v2ex.appspot.com 75–77ms

[upsky]

广州电信
www.v2ex.com 9ms
v2ex.appspot.com 45ms

[upsky]

上面信息有误。
广州电信
www.v2ex.com 9ms
v2ex.appspot.com 95ms

发帖较慢。

[upsky]

从实际感受上来看，appsot比www似乎还快一小点。

[gonbo]

的确是这样，cdn的cache做得不过好，动态内容请求有延迟。


比 http://bbs.you8g.com/ 速度要慢些。

大家可以测试一些。
