I've used both server side rendering and server side includes. A static site generator beats both. Just have a listener that will re-generate the site live when you write new content, then just ssh/ftp the generated content to the server when you are done, or if you are fancy you can use version control and push to a repo with a CI toolchain that will regenerate and ssh/ftp it for you.
