Dumb question or what?

Hi, I am kind of new to php coming from a java servlets background and welll....I have fallen for PHP like a sailer for a hooker after a few months at sea :-) I am going a little crazy with the include() calls and have a template with around 7 includes in the pages like header.php footer.php left.php right.php menu.php news.php misc.php all those files are just static blocks of html code nothing dynamic...my question is (since you guys are much more experienced than me and are using PHP longer) will this be too big a load on the server and/or slow down my page loading a lot in the long run? I have a high speed broadband connection so to me it really does not matter but to the average joe... I have around 13 pages on the whole site... your views are appreciated. Cheers, -Ryan
