I think CF images are caching...

Hmm, CF looks to be way more expensive than S3, which I think is how it is listing out what I saw as data transfer before. I may want to move back off it.

I need to check if we're using thumbnails for the overview view, I suspect not. That's likely a large cost driver given image sizes.

[mooreniemi]

Yeah, we were not using the :medium or :thumb. I switched to :medium for now. Some docs here: https://github.com/thoughtbot/paperclip/wiki/Thumbnail-Generation

Slightly more traffic but now downloaded bytes only 40% of what it was... This should bring CF down in cost to where S3 was before, and I think is acceptable.

Top graph is bytes, bottom is requests.
