I'm currently trying out the Cloudflare CDN (free plan), but I didn't notice much in website performance. My server was having "server load" problems and it did stop, but It seems the website's performance isn't much better.
I believe It's because of my Magento's CDN configuration:
So, which URL's should I use for static files and media files? I can't find information about that on Cloudfare's website and I don't know if I'm really retrieving the static files from there or elsewhere. I use Cloudflare's extension for Magento.
