New server

I want the z0r experience to be as smooth as possible

I don't know if it makes a big difference but you could use the Apache modules 'mod_headers' and 'mod_expires' in addition. You may be able to let the visitor's browser cache the loops but also the includes (scripts, css) at z0r.de. This causes a faster page load if the visitor is using the page periodically. For example you could simply add a "Cache-Control" header to the respond headers when someone requests these files by writing a few code lines into your page's .htaccess.
