As an alternative view, while living in a very unremarkable North American area I have atrocious internet service. I don't think it's particularly uncommon, but it certainly is enlightening to browse the internet. Depending on the time of day a 4MB blob by itself can take ~8 seconds to download. 8 seconds is a _long_ time.

Obviously I have no idea what your app is, I have found very frequently it is not reasonable to have blobs of similar sizes (especially if text content waits for some front end framework to download/initialize).
