利用CDN进行绩效降解。
原标题:Performance degradation using Azure CDN?

我在利用网络成功安装后,对CDN进行试验,我认为这是安全的家。

Why the web-role?

Well, I wanted the benefits of compression and caching headers which I was unsuccessful obtaining using normal blob way. And as an added bonus; the case-sensitive constrain was eliminated also.

<><>>> 在选择了CDN服务时;虽然以前的所有内容都来自同一领域,但现在我越来越多地使用来自cdn.cuemon.net的“静态”内容。 从理论上讲,这应当改进业绩,因为浏览器平行能够将内容收集分散到“多”领域,而只有一个领域。

不幸的是,这导致我认为在满足内容(使用追踪指挥系统)之前,必须减少霍乱的数量。

As you can see from the above trace route, all external content is delayed for quite some time. It is worth noticing, that the Azure service is setup in North Europe and I am settled in Denmark, why this trace route is a bit .. hmm .. over the top?

另一个问题might是,网络网格是另外两个小节;我没有找到时间用两个小小节进行审判,但我知道,微软将小小小节限制在5Mb/s 广域网中,那里小小小小小小小小小小小小小数是100Mb/s。

如果对裁谈会来说,我也感到不快。

任何方面——任何帮助和/或解释都受到高度赞赏。

请允许我指出,我对“空间平台”感到非常满意——我对上述问题感到非常好。

<>Update>

没有――d 选择的新痕迹。

Being inspired by user728584 I have researched and found this article, http://blogs.msdn.com/b/scicoria/archive/2011/03/11/taking-advantage-of-windows-azure-cdn-and-dynamic-pages-in-asp-net-caching-content-from-hosted-services.aspx, which I will investigate further in regards to public cache-control and CDN.

这并不能解释过度的ho积现象,但我希望有技能的网络专业人员能够帮助了解这一问题。

请放心,我将根据我的调查结果随时向你公布。

最佳回答

不要说显而易见的话,但我假定你把Cache-Control HTTP的头盔定在一大批,因为你的内容没有从CDNCache中删除,在你进行追踪测试时从Blob储藏处得到服务?

在您附近有几家服务器,因此,我期望它能做得更好:Windows CDN Node Sites

Maarten Balliauw在CDN(这可能有助于吗?):

如果没有这种帮助,那是有意义的。

问题回答

Okay,在我执行公开控制<>/strong>头盔后,国家航天中心似乎做了预期的工作;从CDN组中的X-数点传送内容。

The above has the constrain that it is experienced - it is not measured for a concrete validation.

然而,这一联系支持我的理论:http://msdn.microsoft.com/en-us/wazplatformtrainingcourse_windowsazurecdn_topic3”rel=“nofollow” http://msdn.microsoft.com/en-us/wazplatformtrainingcourse_windowsazurecdn_topic3

时间对寿命(TTL)规定,对于一个CDN的对口服务器在要求其来源在博龙储存中提供新拷贝之前,要花多少时间进行游说控制。 <>在本期间期满后,新的请求将迫使CDN服务器再次从原来的“

我所假定的挑战是,裁谈会参考的资源仍然汇集了原来的博彩。

Also, credits must be given to this link also (given by user728584); http://blogs.msdn.com/b/scicoria/archive/2011/03/11/taking-advantage-of-windows-azure-cdn-and-dynamic-pages-in-asp-net-caching-content-from-hosted-services.aspx.

伙伴关系。 NET pages, the default conduct is to set cache control to private. 在此情况下,the CD>N将不会满足这一内容。 为了推翻这一行为,使用反应反对改变默认的海滩控制环境。

因此,我迄今为止关于这一微小难题的结论是,你必须密切关注你的切身控制(这种控制经常是出于明显的原因由私人控制)。 如果你利用网络管理方法,TTL每缺72小时,那么你就永远不会经历过我经历过的情况;因此,它只会在外面工作。

由于user728584,请让我朝正确方向指出。
