I have set up the cloud cdn with using storage bucket as a backend.
I have expected to speed up the load by using cdn.
However, it seems cdn makes it even slower significantly.

Those are the same picture and cdn is pointing at the picture below.
However, it results the top one takes 270ms and bottom one takes 90ms.
When I used AWS CloudFront with the same picture it took 40 ms.
I have a feeling that there is something wrong with the caching because the initial time does not differ as the other url does.
However, the console says cache hit is 100%. (and originally it shows N/A and if I query, then 100%)
I did everything in a "recommended" way and also enabled cdn as instructed.
Any idea? or is it an ordinary behavior?
