Yes, I am using cdn for S3.

But I still wondering, if  
does `discourse server(asia) → cdn → users(asia)` faster than `S3(US) → cdn → users(asia)`?

I saw there is a parameter named DISCOURSE\_S3\_UPLOAD\_BUCKET, it looks like a solution to me but after I replace DISCOURSE\_S3\_BUCKET by it. I cannot rebuild my discourse
