Its a question I've been bugging around since many weeks but haven't found a proper answer.
So; I have a traffic monster site with few hundred pages that I occasionally change.
My current language is PHP just to keep headers, sidebar, some boxes and footer in a separate file where I occasionally make minor changes. That's the only job of PHP on my site.
The problem is my 16GB DDR3 RAM never drops below 95% usage!
I have APC installed so my server doesn't needs to render PHP on every request.
If I switch to HTML, will it give me noticeable advantage? (performance and memory consumption)
Ofcourse editing the site would a pain but I can sacrifice that for performance.
Also I'll be using a CDN soon. Does CDN pull HTML and PHP (or atleast PHP caches from APC)?
I hope someone can throw in a proper reply rather than 'I think..' versions!
