James Christie on Sus­tain­able Web Design

At 1.4MB, today’s aver­age page is 15 times larg­er than it was 10 years ago, pri­mar­i­ly due to images (881kB) and script (224kB). Plain old HTML totals just 54kB—but when’s the last time you saw an HTML-only site? This aver­age page also makes more than 100 HTTP requests. Whether they fetch a big object or a small one, these add up to more delay and more pow­er wastage. The aver­age site is also slow: Alexa’s top 2,000 retail­er sites now take an aver­age of more than sev­en sec­onds to load—much longer than users con­sid­er acceptable.

We pub­lished a great issue today, but this par­tic­u­lar arti­cle writ­ten by James Christie caught my eye. I’ve been doing a lot of research into per­for­mance, but I’d stu­pid­ly nev­er thought how slow sites can have an impact on our envi­ron­ment. Site per­for­mance mat­ters; not only to vis­i­tors, but to our planet.
