Best WordPress setup? FastCGI, HHVM (PHP5 Backup), Pagespeed?

I setup REDIS and so far very impressed with the speed increase I have gained.

I am sure HTTP2 and a few other thing from EE have helped also.

Has anyone had any experience with setting up their own CDN to work with REDIS/WordPress? http://community.rtcamp.com/t/create-own-cdn-for-wordpress-with-redis-caching/7003

Thanks
