A static site generator like jekyll or Hugo might be a good option if "real-time" dynamic content is not really needed - e.g. most blogs and news/magazine sites don't need to generate the page everytime (or even every so often then cache it). Just generate it once and serve the HTML. Nothing beats the feel of a static site loading in - so snappy and fast (especially if CSS has been adequately minified/bundled too).
