Thanks for that! I understand the basic issues, but as replacing the entire OS on my server would be needed to get the required underlying support, plus the pain of dealing with otherwise-unnecessary HTTPS, I'd really need some significant gain to bring that work forward, ie it would hurt me at least a little to try to do it! Some of my pages do have tens of images, some have hundreds (eg whiteboxes of thumbnails); at the moment I have pushed a little of that heavy load out to other CDNs but maybe I could bring some of it back with HTTP/2?
