We are using Cloudflare for their SSL and Anti-DDOS protection.
Their SSL license and Anti-DDOS works great.
Their CDN works great too.
I get customers who complain that our XenForo site is slow, times-out often (don't know why) or XenForo loads very slowly with Cloudflare, despite us re-installing XenForo twice, moving to Core i7-2600K with SSD drives.
Does anyone know a CDN network with Anti-DDOS, hacker protection, CDN delivery better than Cloudflare?
