Hi,
We are on the business plan and we purchased the argo feature.
We are discussing this issue with the support over 15 days.
When I change my host file to the ip of the server the speed of the download time is about few ms.
When we use Cloudflare service the first time I browse a page, the download time is in average 15 seconds.
When I browse the same page after that the download time is few ms.
May I ask how large the file which you’re trying to download is and what file extension does it have?
Have you got a download link to try? Did you provided it to the Cloudflare Support?
This might be due to the peering at your local ISP/server.
Check also what does yourdomain.com/cdn.cgi/trace shows, replacing yourdomain.com with your actual domain name of course. Post that, removing the IP, if you want.
Have you checked the Developer Tools (F12) → Console for any errors like mixed content, etc.?
Before moving to Cloudflare, was your Website working over HTTPS connection?
What kind of a content have you got?
Is there a lot of traffic / visitors?
Any images or videos, or embeded iframes?
Is it a WordPress website or some webshop?
Might mean your server is generating a page, therefore upon refresh it gets cached after some particular time and is kept for some time like that n your web browser until it’s expired at the origin host and therefore the server has to re-generate the cached HTML document to serve it again.
However, I might be wrong about it because I don’t have the example URL neither know the domain name to test this out. Therefore, you’ve mentioned you are on a ticket with Business plan, I believe they’d figure and sort this out for you in the meantime.
Was there a lot of traffic on the Website, therefore you might have had to wait “in line” so the server could generate one and serve it to you, despite the Cloudflare?
I ask, because I just wonder due to my curiosity how and why, to figure out or make some connection between the behaviour and case.
May I ask what error do you get? Or that’s the “error” as of the page load time duration?
