So I have been testing the CDN and it really does wonders. However, we were tracking a bug that we resolved by disabling " Enable CDN for Media file". Because of Cross-origin resource sharing, SVG images are not being accessed via CDN. Wouldn’t it make sense to allow users to drill down and specify what comes over CDN and what doesn’t, possibly with wildcards? For us, with media disabled, the site we run has become slow again, making the CDN pointless as we are image-heavy.
