57835 Page optimization w/iframes

Hi - I've got a long copy html salesletter page that needs to be redesigned to have embedded hidden/iframe links in it, so the main page loads quickly, then loads in the 8 iframe html pages as a second step.. There's a total of 8 iframe pages that need to be coded, to load into the main page. in the attachment (looks rough, since 500k max filesize), I show the main page, and in red border, each area that needs to have it's own iframe created. main thing is to speed up the load time of this page, by having some of the segments in it load as embedded frame pages After the first page loads, should speed up the overall load time.. so site visitors can read the top part while the bottom frame parts are loading in.. thanks!
