Cloudflare Images: A missed image takes 2s to load

[ccw]

Hi,

Today I just try to see if hosting images on Cloudflare images will improve the image load speed.

I make two very simple pages:

1. Test page 1: contain an image hosted on our own server(US, LA)
2. Test page 2: contain an image hosted on Cloudflare(Imagedelivery.net)

I use GTMetrix to test from Sydney, Australia.

For Test page 1, even if the image is miss, its load time is only 246ms, see below:

For Test page 2, if the image is miss, the load time is 2.5s, see below:

So, in such a case, why should I use Cloudflare Images since it performs worse than my own server?
