Slow content download times for images

Just a quick counterpoint on NGINX, I've had nothing but good luck with scaling NGINX for php serving and found it much easier to deal with than Apache.

Both benefit from running the latest versions though as HTTP/2 support in each is relatively recent and prioritization wasn't supported in the initial releases. Looking at the nginx changelog there have been a lot of HTTP/2 fixes since 1.10 (though none about prioritization jumped out at me).
