Web developers always say it’s important to speed up a site. Either cut the size of an image, or minimize requests.
Why should we? Everyone has a broadband connection and a fast computer. Why worry about an extra second or two?
First, it’s never just worrying about a second, it’s sometimes worrying about cutting a few milliseconds off a page load. Eliminating 1 HTTP request.
Fixing site perforamance is just as important as doing proper SEO. If you do all the SEO work in the world, Google won’t want to index a slow site.
