Talk:Requests for comment/Reducing image quality for mobile

Impact on infrastructure
Have in mind that depending on how you'll implement this, you may significantly increase imagescaler/Swift/upload CDN requests and storage requirements for Swift. I'm not saying to not do it, but I'd like to see some risk assessment & load estimates in the RFC itself. I'd also very much prefer for this to be blocked on the implementation of the simplify thumbnail cache RFC, as it may alleviate half of my concerns (but not all).

Authors shouldn't have to worry about compression settings
The idea to have authors specify a quality setting, unless I'm fundamentally misunderstanding the intent, seems very misguided. We should write our software to take performance and efficiency considerations into account, not shift that responsibility to authors. If indeed images should be delivered at a higher compression factor / lower quality in certain use cases, let's identify those use cases, and go as far as we can without introducing markup to specify compression settings before even thinking about doing so.--Eloquence (talk) 02:26, 19 March 2014 (UTC)
