90% of your search rank is determined by the number of high-quality sites linking to you. The other 10% is titles, metas, keyword density, on page markup, interlinking between your pages, and finally page load time (in roughly that order). Page load time only becomes a factor after evaluating all of the other factors first. If you're going to spend time doing anything, focus on the 90%, not the last 1%.
