What are the differences between loading a page using CDN and what kind of prodivers are you using? I have much longer loading time to use with cdn. Can I do something wrong or don’t know about something ? maybe i should still set some settings I don’t know about?

CDN will be slower until it gets resources cached. You might wait a while before doing any testing.

Well, the first clue … thanks to . A little bit. How much? We’re talking about days, weeks? Should we force a payload in https or rather http ? I’m asking because there are differences in loading. What does it depend on whether the page is loaded all or looks like the original javascript would hav…

The time frame will depend on how the users interact with the site. The most downloaded assets will get loaded to the CDN caché, and will be faster if you’re closer to the CDN server than from the server. If you have the datacenter next to you, and the CDN server is 1000Km away, it will always be s…

But are we talking about a situation once we add the cdn address to our app.yml file or not ? And what is the reason to use a subdomain for cdn addres? i.e. why can’t it be DISCOURSE_CDN_URL: //637763234.cdn-provider.com and should be discourse-cdn.example.com ??

Are you talking about TTFB on which path exactly? TTFB for a static asset (like a JS file, or a JPG user upload) will always be fast using a CDN, as latency only of the multiple PoP will help with it. TTFB of dynamic routes in the other hand makes no sense to compare, as our DISCOURSE_CDN_URL does…

[图片] Falco: on which path exactly? Can you explain exactly what you mean ? I’m giving the results for the test forum. (btw it’s just come out a little faster) // But it’s only on a fresh domain without content. [image] and for the cloudfront created [image]

What you are seeing is just normal variance. CDN will have no impact on the time to first byte on your the root of your Discourse instance or in any other dynamic route. A CDN will only serve the static assets.

And is there a difference if these resources (static assets) are kept in S3 ?

No, there’s none. The CDN will cache those assets from S3 when needed. [图片] eextra: And what is the reason to use a subdomain for cdn addres? That is just a vanity address, is not needed at all.

你能具体解释一下你的意思吗？

我提供的是测试论坛的结果。（顺便说一句，它只是稍微快了一点）// 但这仅适用于没有内容的崭新域名。
