Are ads displayed on the page from some remote service?  If you haven't 
specified all of the column widths in the HTML layout or if there are 
more than the max number of connections your browser will process at 
once, the display may wait for the images to fill in.   You can have the 
latter problem even with lots of little decorations from your own site. 
  You can diagnose it with a wget of the base page which won't 
automatically pull the images like a browser does.  If it turns out to 
be the server itself, adding RAM and bumping up the number of child 
processes will probably help.  With mostly static pages you should end 
up with the busy parts of the site cached in the filesytem buffers and 
very fast.
