Hi,
I added Cloudflare as CDN mainly for my image data. Unfortunately, its performance is way worse than the one of my server. Take https://forum.milwaukee-vtwin.de/attachments/363/363070.jpeg as an example. This is a 2mb JPEG file which loads in about 500ms from my server. When using https://cdn.milwaukee-vtwin.de/attachments/363/363070.jpeg - which is routed over Cloudflare - then it takes a whopping 7s, sometimes a bit less, sometimes a bit more, although it’s in your cache and I’m using ARGO routing. Is there any problem at your side or am I doing something wrong?
Thanks for your replies. TTFB was not the problem, but low download speed. Apart from that, the results varied too much for me using different providers, so I decided to try another CDN provider. Thanks anyway.
